How to convert Amperes to Milliamperes
Multiply the amperes value by 1,000: 1 A = 1,000 mA. Going the other way, 1 mA = 0.001 A, so divide by 1,000 or use the Milliamperes to Amperes converter.
About these units
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.
Milliamperes (mA)
A milliampere is one thousandth of an ampere. Electronics, LEDs and USB device currents are usually stated in mA.
