About these units
Coulomb (C)
- Definition
- The coulomb (C) is the SI unit of electric charge, defined as the charge transported by one ampere of current in one second.
- History
- Named after French physicist Charles-Augustin de Coulomb, it was formalised with the SI system and redefined in 2019 in terms of the elementary charge.
- Current use
- Coulombs are used in electrochemistry, capacitor ratings, and electrostatics calculations.
Millicoulomb (mC)
- Definition
- A millicoulomb (mC) is one thousandth of a coulomb.
- History
- A metric sub-multiple of the coulomb.
- Current use
- Used in small capacitor and electrostatic discharge calculations.
