Frequently asked questions
How many A are in one mA?
1 mA = 0.001 A.
What is the formula to convert mA to A?
A = mA × 0.001. To go back, mA = A × 1,000.
Why do small electronic loads and chargers quote milliamps?
Signal-level and battery-powered loads draw fractions of an amp, so milliamps give convenient whole numbers. The conversion to amps is a fixed factor and does not depend on the voltage.
