## Explanation

The Planck charge is a measure of electric charge in the Planck unit system. In the section on spacetime, the Planck units are described as the components of spacetime, referred to as *granules*, which can be modeled classically as a spring-mass system to derive fundamental physical constants where only five fundamental constants are required. The following figure describes the relationship of four of these Planck constants.

The Planck charge is a measurement of displacement (wave amplitude) at the first wavelength in the electron’s core when energy is not required for spin. When energy is used for spin, longitudinal displacement decreases (see elementary charge). As a property of wave amplitude, it is correctly measured as a distance (meters), not charge (Coulombs). This simple change allows mass and charge equations to be unified.

## Derivation – Planck Charge

In classical constant format, the Planck charge is one of the five fundamental physical constants that most other constants can be derived. It is set here to the elementary charge, which is not one of the five fundamental constants, to establish its value. It is defined as the elementary charge of an electron divided by the square root of the fine structure constant.

In wave constant format, it is simply based on wave amplitude (A_{l}). Since charge is based on wave amplitude in meters, Coulombs becomes a unit that is measured in meters and not a separate SI unit. Planck charge is the total displacement (peak-to-peak) of a granule. Wave amplitude is equilibrium-to-peak, and is therefore 2 x Planck charge.

**Calculated Value**: 1.8755E-18

**Difference from CODATA:** 0.000%

**Calculated Units**: m

**G-Factor: **g_{A}^{-1}

** Note: **Units are in meters, not Coulombs (C), as wave theory measures charge based on amplitude, which is in meters.

Its value was calculated and shown to match the known value in the Summary of Calculations table. *The derivation of this constant is available in the Fundamental Physical Constants paper.*
