Ampere to Milliampere (A to mA)
Convert A to mA — Electric Current converter
One ampere equals 1000 mA, so to convert amperes to milliamperes you multiply the value by 1000. A ampere is larger than a milliampere — going the other way, 1 mA = 0.001 A. For example, 10 A = 10000 mA and 50 A = 50000 mA.
