## Background

Although it is a ratio of two other constants (proton mass and electron mass), the proton-electron mass ratio is commonly used in physics. Due to similarities of this ratio compared to the ratios of the proton mass and electron mass with the Planck mass, they have been grouped together and shown on one page.

## Energy Wave Constants – Equivalent

The following is the representation of this fundamental physical constant expressed in energy wave theory. Using energy wave constants, its value was calculated and shown to match the known CODATA value.

However, because it requires a different correction factor for the spin g-factor, it is **not included** in the Summary of Calculations table. The spin g-factor used in the calculations for other fundamental physical constants has a correction factor of 0.0000255. To accurately calculate the proton-electron mass ratio value of 1836.15267 requires a correction factor of 0.001055566385 to the spin g-factor. Thus, it was given a symbol Δ_{Ge’ }to note this difference and left out of the Summary of Calculations table. Yet, the similarities of these ratios with a division of amplitude and wavelength across all three ratios is more than a coincidence and so it has been placed here in this section.
