Electromotive force in electrostatic units is the statvolt ( in the centimeter gram second system of units equal in amount to an erg per electrostatic unit of charge ).

The discovery of this relationship started in 1855, when Wilhelm Eduard Weber and Rudolf Kohlrausch determined that there was a quantity related to electricity and magnetism, " the ratio of the absolute electromagnetic unit of charge to the absolute electrostatic unit of charge " ( in modern language, the value 1 / \ sqrt { \ mu _ 0 \ varepsilon _ 0 } ), and determined that it should have units of velocity.
