About Milliampere to Ampere Conversion

This converter converts Milliampere (mA) to Ampere (A). One Milliampere (mA) equals 0.001 Ampere (A).

Formula:

1 Milliampere (mA) = 0.001 Ampere (A)

Example:

1 mA = 0.001 A
2 mA = 0.002 A

Milliampere (mA) to Ampere (A) Conversion

Convert Milliampere to Ampere using the exact conversion factor. This page provides the formula, worked examples, and real-world use cases for practical understanding.

Conversion Formula

Ampere = Milliampere × 0.001

To convert Milliampere (mA) to Ampere (A), multiply the value by 0.001. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 mA to A.

  • Step 1: Write the formula: A = mA × 0.001
  • Step 2: Substitute: 1 × 0.001
  • Step 3: Result: 0.001 A
So, 1 mA = 0.001 A.
