How to use it
- Type the value in the microamperes box.
- Read the result in milliamperes as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
mA = µA × 0.001
Multiply the value in microamperes by 0.001 to get milliamperes.
Example
To convert 25 µA to milliamperes: 25 × 0.001 = 0.025 mA.

About the units
- Microampere
- A microampere is exactly one millionth of an ampere, seen in battery standby currents and precision measurement.
- Milliampere
- A milliampere is exactly one thousandth of an ampere, used for small electronics, sensors and device charging currents.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many milliamperes are in one microampere?
1 µA = 0.001 mA exactly.
How do I convert microamperes to milliamperes?
Use mA = µA × 0.001. For example, 25 µA = 0.025 mA.
How many microamperes are in one milliampere?
1 mA = 1,000 µA.
How many milliamperes are in one ampere?
One ampere is exactly 1000 milliamperes, so a charger rated 2 A delivers up to 2000 mA.
Can I convert amps to watts?
Not directly, because power in watts is current times voltage. A current of 2 A at 5 V gives 10 W.
