Milliamperes to Microamperes Converter

1 milliampere (mA) equals 1,000 microamperes (µA).

Quick answer

1 milliampere = 1,000 microamperes
1 microampere = 0.001 milliamperes
Formula: µA = mA × 1,000

From To 1,000

1 milliampere = 1,000 microamperes

How to convert milliamperes to microamperes

µA = mA × 1,000

To convert milliamperes to microamperes, multiply the number of milliamperes by 1,000.

Example: 18 mA to µA

Start with the value in milliamperes: 18 mA.
Multiply by 1,000: 18 × 1,000 = 18,000.
Result: 18 milliamperes = 18,000 microamperes.

Going the other way, 1 microampere = 0.001 milliamperes, so to convert microamperes back to milliamperes you divide by the same number. See microamperes to milliamperes.
