What is the EMU of charge unit?

EMU of charge, also called abcoulomb (abC), is a unit of electric charge in the centimetre–gram–second electromagnetic system equal to the charge carried by one abampere in one second and corresponds to 10 coulombs in the SI system.

What does the statcoulomb represent?

The statcoulomb (stC) is the electrostatic unit of charge in the Gaussian cgs‑ESU system, used where Coulomb's law does not explicitly include vacuum permittivity.

Why convert between EMU of charge and statcoulomb?

Conversion allows translation of electric charge values between different CGS subsystems used in theoretical physics and historical data, enabling consistent comparison and analysis.
