About Microampere and Milliampere
Microampere (µA)
A microampere is one-millionth of an ampere.
Where it's used: Sleep-mode electronics, sensors, and biomedical devices.
Milliampere (mA)
A milliampere is one-thousandth of an ampere.
Where it's used: Phone charging (500–3000 mA), LED current, and electronics.

µA to mA Formula and Examples
Direct Formula
mA = µA × 0.001 Inverse Formula
µA = mA × 1000 Mental Math Shortcut
Divide the value by roughly 1000 to quickly estimate the converted result.
Common Microampere to Milliampere Calculations
- 5 µA = 0.005 mA
- 10 µA = 0.01 mA
- 50 µA = 0.05 mA
- 100 µA = 0.1 mA
- 500 µA = 0.5 mA
Precision & Practical Use
For example, 10 µA = 0.01 mA — roughly fractional unit measurement.
Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most electric current applications, 2–3 significant figures are plenty.

How to Convert Microampere to Milliampere
How many milliamperes are in one microampere?
One Microampere (µA) equals 0.001 Milliampere (mA). To convert microamperes to milliamperes, multiply the microampere value by 0.001.
How do I convert Microampere to Milliampere?
Multiply your microampere value by 0.001 to get the result in Milliampere: mA = µA × 0.001. For example, 5 µA = 0.005 mA.
What is the formula for converting µA to mA?
The conversion formula is mA = µA × 0.001. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for µA to mA?
Divide the value by roughly 1000 to quickly estimate the converted result.
