Milliamperes to Amperes Converter

1 milliampere is equal to 0.001 amperes, or 0.000001 kA.

Enter a value in the converter to get the result. This page explains the formula, works through examples and lists common values in a conversion table.

How to convert milliamperes to amperes

Multiply the value in milliamperes by 0.001 to get amperes.

A = × 0.001
  1. 1Start with the value in milliamperes: 1 mA.
  2. 2Apply the formula: × 0.001 = 0.001.
  3. 3Round to the precision you need: 0.001 A.

Examples

10 mA to A × 0.001
= 0.01 A50 mA to A × 0.001
= 0.05 A250 mA to A × 0.001
= 0.25 A

About the units

Milliampere (mA)

A unit of current. 1 mA = 0.001 A.

Ampere (A)

A unit of current. 1 A = 1,000 mA.

Accuracy and rounding

The calculation uses exact decimal arithmetic, so the conversion itself adds no error. Results are rounded to six significant figures; the formula steps show more digits.
