How This Converter Works

Convert electric current from milliamperes (mA) to amperes (A). The milli- prefix means one-thousandth, so divide the milliampere value by 1,000. This page also converts amperes back to milliamperes using its reverse direction.

Formula or rule

A = mA ÷ 1,000; mA = A × 1,000

Example

Input
2,500 mA
Calculation
2,500 ÷ 1,000 = 2.5
Result
2.5 A

Notes

The ampere (A) is the SI unit of electric current; the milliampere (mA) is one-thousandth of an ampere. The converter treats current as a non-negative magnitude; signed current may encode direction in a circuit. Current is distinct from electric charge: ampere-hours and milliampere-hours measure charge, not instantaneous current.
