How to convert microamperes to milliamperes

To convert microamperes to milliamperes, multiply the number of microamperes by 0.001.

Formula

mA = µA × 0.001

Examples

  • 5 µA = 5 × 0.001 = 0.005 mA
  • 25 µA = 25 × 0.001 = 0.025 mA
  • 100 µA = 100 × 0.001 = 0.1 mA

Frequently asked questions

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