Milliampere to Ampere (mA to A)

Convert mA to AElectric Current converter

One milliampere equals 0.001 A, so to convert milliamperes to amperes you multiply the value by 0.001. A milliampere is smaller than a ampere — going the other way, 1 A = 1000 mA. For example, 10 mA = 0.01 A and 50 mA = 0.05 A.
