How to Convert Electric Current Units
To perform a conversion, look up the target unit's conversion factor relative to the base unit (ampere). Below are the exact mathematical formulas for the most common electric current unit pairs:
Ampere to Milliampere
mA = A × 1000 Milliampere to Ampere
A = mA × 0.001 Microampere to Milliampere
mA = µA × 0.001 Ampere to Milliampere
mA = A × 1000 Electric Current Unit Conversion Charts
