(electricity) The unit of electric potential and electromotive force in the electrostatic centimeter-gram-second system of units, equal to the potential difference between two points such that the work required to transport 1 statcoulomb of electric charge from one to the other is equal to 1 erg; equal to approximately 299.79 volts. Abbreviated statV.

[Etymology: electrostatic volt] electric potential, electromotive force. Symbol statV. Metric-c.g.s. The electrostatic volt of the e.s.u. system and of the Gaussian system, for a steady current identically statA·statΩ. 1 statV = 299.793~ V.

The statvolt is the unit of voltage and electrical potential used in the cgs system of units. The conversion is
- 1 statvolt = 299.792458 volts.
- (The conversion factor 299.792458 is simply the numerical value of the speed of light in m/s divided by 106.)
It is a useful unit for electromagnetism because one statvolt per centimetre 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, a plane wave 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.
