About the current converter

Electric current is the rate at which charge flows past a point in a circuit, measured in amperes (A) in SI — one amp equals one coulomb per second. Household appliances draw amps to tens of amps, electronic circuits typically operate in milliamperes (mA), and microamperes (μA) appear in low-power sensors and biomedical signals. Older CGS systems use the abampere (= 10 A) and statampere. Use this converter to switch between SI prefixes and the legacy electromagnetic units.

Frequently asked questions

  • What is 1 ampere in everyday terms?

    About what flows through a 100-watt bulb on a 100 V supply. A typical phone charger delivers 1–3 A; an electric kettle draws 10–13 A.

  • Is current the same as charge?

    No. Charge (coulombs) is a quantity of electricity; current (amperes) is the rate at which that charge moves: 1 A = 1 C/s.

  • What is an abampere?

    A CGS-emu unit equal to 10 amperes. It is rare today but appears in old physics textbooks and electromagnetic theory.
