Milliamperes to Amperes Converter

1 milliampere (mA) equals 0.001 amperes (A).

Quick answer

  • 1 milliampere = 0.001 amperes
  • 1 ampere = 1,000 milliamperes
  • Formula: A = mA ÷ 1,000

1 milliampere = 0.001 amperes

How to convert milliamperes to amperes

A = mA ÷ 1,000

To convert milliamperes to amperes, divide the number of milliamperes by 1,000.

Example: 42 mA to A

  1. Start with the value in milliamperes: 42 mA.
  2. Divide by 1,000: 42 ÷ 1,000 = 0.042.
  3. Result: 42 milliamperes = 0.042 amperes.

Going the other way, 1 ampere = 1,000 milliamperes, so to convert amperes back to milliamperes you multiply by the same number. See amperes to milliamperes.
