Statvolt
The statvolt is a unit of voltage and electrical potential used in the CGS-ESU and gaussian systems of units. In terms of its relation to the SI units, one statvolt corresponds to exactly c_cgs e-8volt, i.e. to 299.792458 volts. The statvolt is also defined in the CGS system as 1 erg / statcoulomb. It is a useful unit for electromagnetism because, in a vacuum, an electric field of one statvolt per centimetre has the same energy density as a magnetic field of one gauss.
Abampère
The abampere (abA), also called the biot (Bi) after Jean-Baptiste Biot, is the derived electromagnetic unit of electric current in the emu-cgs system of units (electromagnetic cgs). One abampere corresponds to ten amperes in the SI system of units. An abampere of current in a circular path of one centimeter radius produces a magnetic field of 2π oersteds at the center of the circle. The name abampere was introduced by Kennelly in 1903 as a short name for the long name (absolute) electromagnetic cgs unit of current that was in use since the adoption of the cgs system in 1875.
