How to convert milliamperes to microamperes
To convert milliamperes to microamperes, multiply the number of milliamperes by 1000.
Formula
µA = mA × 1000
Examples
- 5 mA = 5 × 1000 = 5000 µA
- 25 mA = 25 × 1000 = 25000 µA
- 100 mA = 100 × 1000 = 100000 µA

Frequently asked questions
- How many microamperes are in one milliampere?
- One milliampere is exactly 1000 microamperes.
- How do I convert microamperes to milliamperes?
- To convert microamperes to milliamperes, multiply the number of microamperes by 0.001. The formula is mA = µA × 0.001.
- Is this conversion exact?
- Yes. Both units have exact definitions and the factor 1000 is exact. Displayed results are only rounded when they have many decimal places.
- Which is larger, a milliampere or a microampere?
- A milliampere is 1000 times larger than a microampere. In other words, a microampere is exactly 1/1000 of a milliampere.
