How to convert milliamperes to amperes

To convert milliamperes to amperes, multiply the amount in milliamperes by 0.001. For example, 10 mA = 0.01 A. To convert in the other direction, divide by the same factor, or use the ⇄ swap button above.

Convert electric current between amperes, milliamperes and CGS units. The ampere is the SI base unit of electric current.
