How to convert Milliamperes to Amperes
Multiply the milliamperes value by 0.001: 1 mA = 0.001 A. Going the other way, 1 A = 1,000 mA, so divide by 0.001 or use the Amperes to Milliamperes converter.
About these units
Milliamperes (mA)
A milliampere is one thousandth of an ampere. Electronics, LEDs and USB device currents are usually stated in mA.
Amperes (A)
The ampere is the SI base unit of electric current, defined by fixing the elementary charge. A phone charger supplies about 1 to 3 A, and a household circuit is typically 15 to 20 A.
