Constans Coulombiana

Constans Coulombiana,^[1] vel constans roboris electricae,^[2] vel constans electrostatica^[3] ( $k e$ vel $k$ vel $K$ notata) est constans proportionalitatis in aequationibus electrostaticae^(en)(d) adhibita.^[4] Nomen in honorem physici Francogallici Caroli de Coulomb (1736–1806) electum est, qui legem Coulombianam^(d)(en) anno 1785 invenit.^[5]

Secundum unitates primarias Systematis internationalis unitatum, constanti Coulombianae congruunt 8.9875517923(14)×10⁹ kg m³ s⁻⁴ A⁻².^[6]

Secundum nonnulla systemata unitatum naturalium^(en)(d) (e.g. secundum unitates Stoneyanas, secundum unitates Planckianas), constans Coulombiana partem numeralem habet unius – i.e.: $k e = 1 l S 3 m S t S -2 q S -2 = 1 l P 3 m P t P -2 q P -2 = \dots$
