is the unit of voltage
and electrical potential
used in the cgs
system of units. The conversion is
- 1 statvolt = 299.792458 volts.
It is a useful unit for electromagnetism
because one statvolt per centimeter is equal in magnitude to one gauss
. Thus, for example, an electric field
of one statvolt/cm has the same energy density as a magnetic field
of one gauss. Likewise, light propagating in a vacuum has perpendicular electric and magnetic fields such that for every gauss of magnetic field intensity there is one statvolt/cm of electric field intensity.
