Electrostatic units

The electrostatic system of units (ESU) is a system of units used to measure quantities of electric charge, electric current, and voltage within the centimeter-gram-second (or "CGS") system of metric units. In electrostatic units, electrical charge is defined by the force that it exerts on other charges.[1][2]

Although the CGS units have mostly been supplanted by the MKSA (meter-kilogram-second-ampere) or International System of Units (SI) units, the electrostatic units are still in occasional use in some applications, most notably in certain fields of physics such as in particle physics and astrophysics.
