Describing Coulomb’s Constant

Using Only the Fundamental Measures

ABSTRACT

We derive Coulomb's constant from first principles using the MQ fundamental measures and their associated count relations. The derivation begins with the 2022 CODATA recommended values of the fine-structure constant, electron mass, and Bohr radius together with the defined speed of light, from which the MQ mapping parameter, fundamental measures, and Frames mapping factor are determined. These quantities are then used to successively derive the interaction-length count, inverse fine-structure constant, elementary charge, vacuum electric permittivity, and finally Coulomb's constant. The resulting expression,
ke=γFmftf2/(2lf3)
, depends only upon the MQ fundamental measures and the dimensionless Frames mapping factor. Evaluation yields ke = 8.987551802(610) × 109 N m2 C-2, in agreement with the 2022 CODATA recommended value within the calculated uncertainty. The derivation exposes a common fundamental-measure structure shared by Coulomb's constant and the MQ expression for gravitational curvature while distinguishing this algebraic correspondence from any physical identification of electromagnetic and gravitational phenomena. Unlike previous MQ implementations, the Frames mapping factor is derived independently of the electromagnetic quantities subsequently evaluated, removing the circular dependency associated with earlier formulations. These results provide a first-principles description of Coulomb's constant based on the MQ fundamental measures and demonstrate that the elementary charge, vacuum electric permittivity, and Coulomb's constant emerge as predictions of the MQ framework rather than as quantities used to establish it.

1. INTRODUCTION

Coulomb's constant ke is the proportionality constant appearing in Coulomb's law and, in SI units, is conventionally expressed as
ke=(4πε0)-1
, where ε0 denotes the vacuum electric permittivity [1]. We present a description of ke using only the fundamental measures defined within Measurement Quantization (MQ). The central objective is to determine whether Coulomb's constant can be resolved entirely from these measures and their count relations.

The MQ construction begins with the properties assigned to measure and the relations used to resolve them. Discrete expressions describing gravitational curvature, the speed of light, escape velocity, and Heisenberg's uncertainty principle [2] are evaluated using the dimensionless counts nL, nM, and nT of the fundamental length, mass, and time measures lf, mf, and tf, respectively. The parameter θsi denotes the MQ mapping parameter relating these measures through the Frames mapping. Within MQ, the simultaneous solution of these relations identifies measure as discrete and countable in the Internal Frame.

The count values and fundamental measures are not assigned independently in the derivation. Instead, they are obtained from the joint constraints imposed by the four physical relations. The resulting fundamental measures ([3], Appx. W) refine the corresponding Planck unit constructions by incorporating the Informativity differential and the non-Lorentz length contraction contribution associated in MQ with discrete realization ([3], Appx. D).

The frame dependence of this construction is developed in ([3], Appx. K). The Internal Frame is the discrete configuration domain in which measure is represented through counts of the fundamental measures. The System Frame is the continuous physical realization produced by the Frames mapping (Appx. A). MQ attributes the difference between these descriptions to the Frames mapping, which enters its expressions for observable physical constants [4]. Coulomb's constant provides the electromagnetic example examined here.

Let c denote the speed of light in vacuum and let γF denote the dimensionless Frames mapping geometry factor derived later in the paper. Coulomb's constant is then obtained as

ke=mflfc216γF=8.987551802(610)109Nm2C-2.
(1)

The purpose of this paper is to derive Eq. (1), including the independent construction of γF, and to compare the resulting value with the accepted value of Coulomb's constant.

2. METHODS

This paper applies the MQ count formalism to the established expressions for gravitational curvature, the speed of light, escape velocity, Heisenberg's uncertainty principle, the fine structure constant, elementary charge, vacuum electric permittivity, and Coulomb's constant. MQ expresses these relations in terms of counts of the fundamental measures and their realization under the Frames mapping. Previous applications of this methodology are presented in Refs. [3, 5–9].

The MQ realization adopted in this work is established from the 2022 CODATA recommended values of the fine structure constant, electron mass, and Bohr radius together with the defined value of the speed of light. These source measurements determine the MQ mapping parameter, the fundamental measures, and the Frames mapping. The same framework is then used to derive all remaining constants. None of the latter quantities participates in establishing the MQ framework used to derive them.

The derivation therefore distinguishes between source quantities used to establish the MQ realization and quantities subsequently predicted by that realization. Agreement with experimentally accepted values is assessed through concordance analysis. Although the 2022 CODATA recommended constants are obtained through a least-squares adjustment and therefore exhibit statistical covariance, the physical quantities compared remain independent observables. The reported concordance should therefore be interpreted as a measure of agreement between the MQ framework and accepted physical constants while recognizing the covariance introduced by the CODATA adjustment.

The MQ framework is also evaluated alongside the corresponding classical framework by expressing the same physical relations using their respective systems of fundamental units. Classical expressions are converted in the same manner as conventional Planck unit formulations, whereas MQ expressions are derived from the right-angle triangle construction and explicitly incorporate the Frames mapping between the Internal Frame and the System Frame. Because the MQ framework adds a prediction of non-Lorentz length contraction which greatly differs between electromagnetic and macroscopic phenomena, the resulting concordance provides a direct comparison of their ability to describe the same physical phenomena when both electromagnetic and macroscopic constants are used in the same description. In the present work the MQ framework yields an overall concordance of 8.74σ, whereas the corresponding classical framework yields no statistically significant concordance.

The MQ premises concerning discrete and countable measure are developed in the introductory summary publication Measurement Quantization [3]. Rather than reproducing those derivations here, this paper builds upon the specific MQ constructions listed in Table 1.

These spreadsheets include all intermediate calculations, uncertainty propagation, concordance analysis, and numerical implementations required to reproduce the reported results.

Because several MQ derivations require numerical precision exceeding the approximately 15 significant digits provided by standard spreadsheet arithmetic, all calculations are performed using the XLPrecision PrecisionCalc Excel plug-in.

The supplementary spreadsheets therefore constitute the complete computational record supporting every numerical result presented in this paper.

3. RESULTS

A solution for Coulomb's constant is obtained by successively resolving the intermediate quantities required by the MQ construction using only the fundamental measures. The derivation begins with the count relations associated with the electromagnetic demarcation and proceeds through the corresponding Frames mapping quantities.

3.1. Supporting Expressions

Within MQ, the blackbody, charge coupling, and elementary charge demarcations provide independent determinations of a common interaction length count nL. The blackbody demarcation is developed in ([3], Appx. AB), the charge coupling demarcation in ([3], Appx. AE), and the elementary charge demarcation in ([3], Appx. AN). These determinations resolve nL to approximately the common value of 84.60055+. For the blackbody demarcation,

nL=θsilf1ℏ(ℏ-2θsilf)=84.60055.
(2)

Here, nL denotes the interaction length count, lf the fundamental length, tf the fundamental time, ħ the reduced Planck constant, and θsi the MQ mapping parameter.

At the whole-count level this relation yields,

nθ=⌊nL/2⌉=⌊84.60055/2⌉=42.
(3)

The interaction length count nL=84.60055 therefore corresponds to nθ=42. The charge coupling demarcation ([3], Appx. AE) provides the interaction length determination adopted in this derivation:

nL=276/θsi=84.60055.
(4)

And with these expressions we resolve the value of θsi ([3], Appx. AD) as a function of the 2022 recommended value for the fine structure constant [10],

2αc=1nLθsiθsi(θsi2+(nLθsi)2)1/2-nLθsiθsi(84θsi-⌊42θsi⌉).
(5)

Evaluating this expression gives

θsi=3.262390305(36)kgms-1.
(6)

The corresponding count then determines the metric differential,

nθ=42θsi-⌊42θsi⌉,
(7)

as defined in ([3], Appx. T).

Application of the non-Lorentz length contraction construction developed in ([3], Appx. D) resolves the contraction associated with the discrete Internal Frame,

QLnL=nL((1+nL2)1/2-nL)=0.4999825.
(8)

QL denotes the fractional length count contribution. The product 2QLnL is more commonly known as the Informativity differential.

3.2. Inverse Fine Structure Constant

The three inverse fine structure forms are described by the fundamental definition, mapped to its realized Planck-like form, and then to its classical form after accounting for the non-Lorentz length contraction associated with the discrete Internal Frame ([3], Appx. AA),

αf-1=42θsi,
(9)
αp-1=84θsi-⌊42θsi⌉,
(10)
αc-1=2QLnL(84θsi-⌊42θsi⌉).
(11)

Their calculation yield a 3.45σ concordance with the 2022 CODATA recommended values. Each are dimensionless. Accordingly, θsi is used here as the dimensionless System Frame mapping parameter.

3.3. Elementary Charge

3.3.1 Fundamental elementary charge

The MQ construction begins with the fundamental form of the elementary charge ef. The 2022 CODATA recommended values for the fine structure constant, the mass of an electron and the Bohr radius provide the basis for the calculated value of θsi. When comparing the MQ calculation of the fine structure constant to its measure, we use and independent determination [11] distinct from the CODATA recommendation [10]. The identification of that geometry with the mapping parameter θsi is made within MQ through a momentum description of θsi ([3], Appx. Q), rather than constituting an experimental determination of ef.

For this derivation, b denotes the unmapped base quantity associated with the fundamental charge expression, while d denotes the metric differential applied in passing between the corresponding frame representations. The base is written as the fundamental charge ef multiplied by the mapped fundamental mass function f(mf), relative to the factor ħ/2, where ħ is the reduced Planck constant entering the MQ momentum construction. The mapping parameter satisfies θsi=lfmf/2tf, through its momentum description ([3], Appx. Q). The mapped fundamental mass function is reduced using the mass relation given in ([3], Appx. V). These substitutions provide the first principles reduction from the temporary quantities b, d, and f(mf) to an expression involving only ef, θsi, and the fundamental measures.

bd≡b-d,
(12)
bd=ef(f(mf)ħ/2)=efmf2(2θsilf)/2=efmf2θsilf,
(13)
efmf2θsilf=efmf2lf-θsi,
(14)
ef(mf2θsi-mf2)=lfθsi2,
(15)
ef=lfθsi2mf2(θsi-1)=lf34tf2(θsi-1),
(16)
ef=14(θsi-1)lfc2,
(17)

We identify this as the MQ fundamental form of elementary charge. It precedes both the non-Lorentz length contraction and the System Frame realization contribution.

3.3.2 Quantized and Classically Realized Elementary Charge

The quantization construction begins with a determination of metric differential associated with the count difference associated with the Frames mapping parameter,

nθ=42θsi-⌊42θsi⌉.
(18)

This resolves the discrete count adjustment to a fundamental charge construction. The corresponding elementary charge remainder ne is formed from ef by the same construction as the inverse fine structure constant,

ne=84ef-⌊42ef⌉.
(19)

Here we take the offset due to the Frames mapping – resolved respect to θsi in Eq. (19) – and subtract that from the initial measure (same as we do in the fine structure constant construction). The difference is a factor of two in the first term.

The Planck-like elementary charge is then obtained by

ep=ne84+42(276+1)-3nθ-7nθ2-14nθ3.
(20)

where the realization divisor is constructed from the repeating Diophantine realization sequence associated with the electromagnetic count. The whole-unit realization is specified by the integers 84 and 42, the inclusive reference count domain is given by 276+1, and the polynomial term introduces the dependence of the realization function on nθ. The resulting mapping converts the elementary-charge residual ne defined in the Internal Frame into the Planck-like elementary charge ep, corresponding to its System Frame realization.

The classically realized elementary charge is resolved by application of the contraction Δ(P-C)

Δ(P-C)=ep(1-2QLnL).
(21)

The classically realized elementary charge is consequently

ec=ep-Δ(P-C),
(22)
ec=ep-ep(1-2QLnL)=2QLnLep,
(23)
ec=2QLnLep=1.602176633(47)10-19C.
(24)

This completes the sequence from the MQ fundamental form ef, through the mapped Planck-like form ep, to the classically realized elementary charge ec.

3.3.3. Electric Constant

The vacuum electric permittivity ε0 is conventionally related to the vacuum magnetic permeability μ0 and the speed of light by ε0=1/(μ0c2). It may also be expressed through the elementary charge, fine structure constant, Planck constant, and speed of light. Using ħ=h/(2π), the latter relation is written as

ε0=1μ0c2=ec22hαcc=1ℏec24παcc=QLnLθsilfec24παcc.
(25)

Substitution of the inverse classical form of the fine structure expression from Eq. (11) gives

ε0=2QLnL(84θsi-⌊42θsi⌉)QLnLθsilfec24πc,
(26)

and collection of common factors yields

ε0=(QLnL)2(84θsi-⌊42θsi⌉)2πθsilfcec2.
(27)

Such that ec follows from Eq. (24), ec=2QLnLep, then

ε0=(QLnL)2(84θsi-⌊42θsi⌉)2πθsilfc(2QLnLep)2.
(28)

The terms describing the count geometry – Planck form of elementary charge, MQ form of the inverse fine structure constant, and the Informativity differential are then collected into the dimensionless Frames mapping factor,

γF=(84θsi-⌊42θsi⌉)((QLnL)284ef-⌊42ef⌉84+(42/((276+1)-3nθ-7nθ2-14nθ3)))2.
(29)

This then reduces vacuum electric permittivity to

ε0=4γFπlfmfc2=8.85418780(60)10-12Fm-1.
(30)

3.3.4. Calculations

Coulomb's constant is conventionally defined in SI by ke=1/4πε0. Substitution of Eq. (30) gives

ke=14πε0=14ππmflfc24γF=mflfc216γF,
(31)

and hence

ke=mflfc216γF=8.987551802(610)109Nm2C-2.
(32)

For comparison, the 2022 CODATA recommended value is ke = 8.9875517862(14) × 109 N m2 C-2, a difference of 15.8 N m2 C-2. We can expression this in terms of the gravitational constant by introducing terms,

ke=mflfc216γF=mflf16γFc3tflfmfmf=mf216γFc3tfmf.
(33)

Such that the MQ description of the gravitational constant is

G=c3tfmf,
(34)

we can then substitute this into Eq. (33) to find that

16γFke=Gmf2.
(35)

This establishes the algebraic relation between Coulomb's constant and the MQ expression for gravitational curvature through the common fundamental measures and the Frames mapping factor γF. It does not by itself establish that electric charge is gravitational curvature; that physical interpretation requires a separate MQ derivation associated with the frame relation.

4. DISCUSSION

Coulomb's constant is conventionally related to the vacuum electric permittivity through ke=1/(4πε0). The factor 4π reflects the spherical solid-angle normalization of the electric flux produced by a point charge in three spatial dimensions. Within the MQ factorization ke=γFmf/(2c2lf), the same constant is reorganized in terms of the fundamental measures and the Frames mapping factor γF. This reorganization does not replace the conventional electromagnetic relation. Rather, it exposes a first principles construction based on the discrete count structure developed throughout the paper.

Unlike previous MQ implementations, the Frames mapping factor is not obtained from one of the electromagnetic constants whose values are subsequently reproduced. Instead, the derivation begins with the experimentally determined 2022 CODATA recommended values of the fine structure constant, electron mass, and Bohr radius together with the defined speed of light. These quantities determine the MQ mapping parameter, the fundamental measures, and the Frames mapping factor before the elementary charge, vacuum electric permittivity, and Coulomb's constant are derived. The resulting derivation therefore removes the circular dependency associated with determining γF from the same electromagnetic quantities later evaluated.

The revised SI remains important when interpreting the comparison with experiment. Following the 2019 redefinition [12], the numerical values of the speed of light c, Planck's constant h, and the elementary charge e are exact defining constants, whereas the vacuum magnetic permeability μ0, vacuum electric permittivity ε0, and Coulomb's constant inherit the experimental uncertainty of the fine structure constant through the CODATA adjustment. Within the MQ framework, however, neither the elementary charge, the electric constant, nor Coulomb's constant participates in constructing the derivation. Agreement between the MQ values and the 2022 CODATA recommended values therefore represents a successful prediction of these electromagnetic quantities from an independent set of source measurements rather than the reproduction of quantities already used as MQ inputs.

The practical significance of the Frames mapping factor is therefore no longer its use as a fitted electromagnetic parameter but as a quantity emerging directly from the MQ count structure. It collects the count geometry, quantization ratio, and Informativity differential into a single dimensionless quantity determined prior to the electromagnetic derivation. Coulomb's constant consequently becomes the final quantity in the derivation, allowing direct comparison with the 2022 CODATA recommended value.

The elementary charge construction also differs algebraically from the usual application of the metric differential used for the inverse fine structure constant ([3], Appx. T; Appx. AA). For the fine structure constant, the frame adjustment is represented by an additive difference of the form b-d. In the elementary charge derivation, Eqs. (14–19) instead use the quotient relation b/d=b-d at the applicable count bound. This relation permits the fundamental form of the elementary charge ef to be reduced before the discrete adjustment is applied through the quantization ratio rq. The quotient construction therefore changes the implementation of the metric differential while preserving the subsequent application of the Informativity differential required to obtain the classically realized elementary charge.

An additive construction analogous to that used for the inverse fine structure constant cannot presently be inferred directly from ef=lfc2/[4(θsi-1)]. The MQ mapping parameter satisfies θsi=lfmf/(2tf), but the elementary charge expression has not been independently reduced to a pure whole-count expression in θsi. Consequently, assigning an additive offset of the form b-d would introduce an unestablished count relation. The quotient construction used in Eqs. (14–19) should therefore be regarded as the canonical derivation of ef, rather than as an interchangeable reformulation of the fine structure construction.

Keywords

Internal Frame

The Internal Frame is the discrete, count–based configuration domain in which all fundamental measures are defined relative to the fundamental units lf, mf and tf. All relational structure is encoded as integer count configurations over this domain. The Internal Frame does not possess a continuous geometric structure; rather, geometry arises only through its mapping into the System Frame.

System Frame

The System Frame is the non–discrete, relational encoding of Internal Frame structure induced by the Frames mapping. It does not possess an independent fundamental measure but instead represents observable quantities as continuous relational separations derived from discrete count structure. All physically meaningful observables are defined in the System Frame.

Frames mapping

The Frames mapping is the kinematic transformation that relates discrete count configurations in the Internal Frame to continuous relational structure in the System Frame. This mapping preserves realization consistency and enforces closure conditions on relational configurations. Observable quantities arise only after application of the Frames mapping, and all geometric and interaction structure emerges from its properties.

Frames Principle

The Frames Principle asserts that all physically meaningful observables arise from the Frames mapping between the Internal Frame and the System Frame. No observable quantity is intrinsic to the Internal Frame alone. All measurement is relational and defined through the mapping. This principle replaces the assumption of a pre–existing spacetime manifold with a kinematic origin of geometry.

MQ Action

The MQ Action is the fundamental kinematic functional defined over the Internal Frame count structure. It governs the evolution and consistency of relational configurations under the Frames mapping. The action admits distinct realizations determined by count separation: fixed interaction–scale realizations, corresponding to electromagnetic behavior at the electromagnetic demarcation, and count–resolved realizations, corresponding to gravitational behavior through the mapping–induced metric structure. In both cases, observable dynamics arise from the normalization and realization of conserved count under the mapping. All emergent physical behavior, including electromagnetic interactions and gravitational curvature, therefore arises from this single action without the introduction of any independent dynamical components.

MQ variational principle

The MQ variational principle states that physically realized configurations in the System Frame correspond to stationary points of the MQ action functional defined over admissible realizations of encoded availability derived from the Internal Frame, thereby replacing the independent postulation of dynamical laws with a single extremization condition from which all effective interactions emerge. Formally, let M:ω→ℛ denote the Frames mapping, and let ω'⊂ω be a relational region of the Internal Frame with realized configuration Ω=M(ω')⊂ℛ. Let ρR denote the corresponding coarse–grained encoded availability field. The MQ action is defined as the functional

S[ρℛ]=∫ℛℒ(ρℛ,∂ρℛ,…)dμ,
where ℒ is constructed from count–based relations induced by the mapping M, and dμ is the induced measure on ℛ. The MQ variational principle asserts that admissible realizations satisfy δS=0 under variations consistent with the constraints of the Frames mapping and the conservation relations defined on ω'.

Informativity differential

The Informativity differential is the non–Lorentz length contraction associated with the discrete count structure of the Internal Frame. It arises from the normalization of conserved count under the Frames mapping and quantifies the difference between relational separation in the Internal Frame and its realized representation in the System Frame. The magnitude of the effect is count–dependent, increasing at small separations and diminishing toward the upper–count limit. The Informativity differential is distinct from curvature and represents one of the two geometric consequences of realization in the System Frame, the other being the emergent curvature associated with count loss under successive updates.

Metric differential

The metric differential characterizes the discrete–continuous mismatch that arises when conserved Internal Frame count structure is realized as a continuous observable in the System Frame under the Frames mapping. It does not represent a physical deformation in itself but rather the necessity of expressing integer–resolved count relations as normalized, non–discrete quantities.

For a fundamental measure defined by a count n in the Internal Frame, realization in the System Frame requires application of a mapping normalization functional. This process preserves count conservation while enforcing continuity, introducing a representation–level mismatch between the discrete count structure and its continuous encoding. The metric differential refers to this mismatch as a structural consequence of the mapping.

The metric differential is therefore distinct from the Informativity differential. While the Informativity differential describes a non–Lorentz length contraction in realized separations, the metric differential captures the underlying requirement that discrete count relations be expressed in a continuous form. In this sense, it provides the count–level representation of the discrete–continuous correspondence enforced by the Frames mapping, whereas the Informativity differential describes its realized geometric manifestation in the System Frame.

Electromagnetic demarcation

The electromagnetic demarcation is the fixed interaction count distance nL = 276/θsi, corresponding to approximately 84.60055lf, at which known electromagnetic interactions are realized in MQ. At this scale, the effect of the Informativity differential is still significant. Its influence increases with decreasing interaction distance and rapidly diminishes with increasing distance, becoming physically negligible beyond a few hundred counts of lf. The electromagnetic demarcation is the fixed electromagnetic interaction scale at which that discrete measure effect is realized.

Count separation

The number of fundamental length units lf between relational configurations in the Internal Frame. This quantity determines the scale at which mapping–induced deformation becomes significant.

Realization manifold

A realization manifold is the set of all admissible System Frame realizations compatible with a specified Internal Frame configuration under the Frames mapping ℛ(ΩI). The realization manifold is not a primitive geometric object of the Internal Frame. Rather, it is the image of conserved Internal Frame count structure after application of the Frames mapping and any applicable realization constraints. Probabilities are assigned only after a normalized measure is defined on the admissible realization manifold.

Mapping–induced deformation

The modification of realized separation in the System Frame arising from the discrete–continuous Frames mapping between the Internal Frame and the System Frame. This deformation is fully determined by the mapping structure and does not constitute an independent physical field. It has two coupled manifestations depending on the scale of the interaction. At fixed count separation, it appears as a local, scale–invariant modification governed by the Informativity differential, corresponding to the non–Lorentz contraction of realized lengths. Over extended count separation, the same mapping–induced deformation accumulates through the mapping structure and is realized as geometric curvature in the System Frame. These two manifestations are not distinct mechanisms but represent different scale–dependent realizations of a single underlying mapping effect.

Fixed interaction scale

A fixed interaction scale is a count–defined interaction distance at which a physical interaction is realized under the Frames mapping. For electromagnetic interactions, this occurs at the electromagnetic demarcation nL = 276/θsi, where the interaction is evaluated at a single, fixed count separation. At this scale, both the Informativity differential (non–Lorentz length contraction) and the corresponding curvature are realized with fixed values determined by the mapping. The interaction therefore reflects a specific point in the discrete count structure rather than a limiting regime.

Curvature–resolved regime

A curvature–resolved regime refers to the dependence of realized geometric structure on count separation under the Frames mapping. In this description, curvature is a direct consequence of the mapping evaluated at a given count distance. Different separations correspond to different realized curvature values in the System Frame, providing a geometric description of interaction that varies with count scale. This behavior characterizes gravitational phenomena, where measurements probe a range of separations rather than a fixed interaction scale.
