Question

what is unit of charge? ​

Answer 1

The statcoulomb (statC) or franklin (Fr) or electrostatic unit of charge (esu) is the physical unitfor electrical charge used in the esu-cgs (centimetre–gram–second system of units) and Gaussian units. It is a derived unit given by

It can be converted using

1 newton = 105 dyne1 cm = 10−2 m

The SI unit of charge is the coulomb (C). The conversion between C and statC is:

1 C = 2997924580 statC ≈ 3.00×109 statC

1 statC = ~3.33564×10−10 C.

The number 2997924580 is 10 times the value of the speed of light expressed in meters/second
