# Abcoulomb

From Knowino

*See also statcoulomb (also known as esu)*

The **abcoulomb** (symbol **abC**) is the unit of electric charge in the cgs-emu (centimeter-gram-second electromagnetic) system of units. One abcoulomb is the charge transported in a current of one abampere (abA) in one second: 1 abC = 1 abA × 1 s. Since 1 abA is 10 ampere (A) and 1 coulomb (C) is 1 A⋅s, it follows that

- 1 abC = 10 C
