<P> Coulomb 's constant , the electric force constant , or the electrostatic constant ( denoted k , k or K ) is a proportionality constant in electrodynamics equations . In SI units , it is exactly equal to 7009898755178736817 ♠ 8987551787. 368 1764 N m C , or roughly equaling 7009899000000000000 ♠ 8.99 × 10 N m C. It was named after the French physicist Charles - Augustin de Coulomb ( 1736 -- 1806 ) who introduced Coulomb 's law . </P>
