Coulomb's Constant

Coulomb's Constant (k_e) is 8987551787.3682 m/F

The Math / Science

Coulomb's constant, the electric force constant, or the electrostatic constant (denoted ke ) is a proportionality constant in equations relating electric variables and is exactly equal to `ke  = 8.9875517873681764×10^9 Nm^2/C^2 (m/F)`. It was named after the French physicist Charles-Augustin de Coulomb (1736–1806) who first used it in Coulomb's Law.
Coulomb's Constant  is used in electromagnetic theory to relate electrical variables.

This constant, `k_e`, is given by:

`k_e =  1/ (4*pi*epsilon_0)`, where `epsilon_0` is the electric permittivity of free space
