Convert amperes, milliamperes, microamperes and kiloamperes.
Electric current
The unit of electric current is the ampere (A). Household circuit breakers are typically rated 10–16 A, while phone charging currents are often given in mA. Conversions are decimal: 1 A = 1,000 mA, 1 mA = 1,000 µA and 1 kA = 1,000 A. Current relates to voltage and power by P = U × I.
