How to convert milliamperes to microamperes
µA = mA × 1,000Multiply the value in milliamperes by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A milliampere is larger than a microampere: one milliampere contains 1,000 microamperes.

About the units
Milliampere (mA)
The milliampere (mA) is a unit of electric current in the International System of Units (SI). One milliampere equals 0.001 amperes (A).
Microampere (µA)
The microampere (µA) is a unit of electric current in the International System of Units (SI). One microampere equals 0.000001 amperes (A).
Frequently asked questions
How many microamperes are in one milliampere?
There are 1,000 microamperes in one milliampere, and this value is exact by definition.
How do I convert milliamperes to microamperes?
Multiply the number of milliamperes by 1,000. For example, 10 mA × 1,000 = 10,000 µA.
How many milliamperes are in one microampere?
One microampere equals 0.001 milliamperes. That is the reverse factor, 1 ÷ 1,000.
What is 10 milliamperes in microamperes?
10 mA = 10,000 µA.
Is this mA to µA converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
