What is the mks and cgs units for VOLTAGE?

In the MKS (meter-kilogram-second) system, voltage is measured in volts (V), where 1 volt is defined as 1 joule per coulomb (1 V = 1 J/C). In the CGS (centimeter-gram-second) system, voltage is measured in statvolts (abbreviated as statV), where 1 statvolt is defined as 1 erg per electrostatic unit of charge (1 statV = 1 erg/statC).
