## Main Question or Discussion Point

Coulomb's Law states F = q**2/ r**2

q= statCoulombs

In SI units, F = Ke (q**2/r**2)

q= Coulombs

I read that 1 C = 2.997 x 10E+09 statC

Then Ke = 8.987 x 10E+09

(1) Does anyone know where the conversion for C to statC came from?

(2) and how you get the Ke from those values?

Thanks!
