How the formula works
Both milliampere and microampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliamperes by 1000 to get microamperes. To reverse the conversion, multiply a microampere value by 0.001 to get back to milliamperes.
Frequently asked questions
What is Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
What is Microampere (uA)?
A Microampere (uA) equals 1e-06 ampere(s), a scaled unit of electric current used for micro-scale electrical work.
How do I convert milliamperes to microamperes?
Multiply the milliampere value by 1000 to get the equivalent in microamperes. For example, 5 mA × 1000 = 5000 uA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert microamperes back to milliamperes?
Yes. Divide the microampere value by 1000, or multiply it by 0.001, to get milliamperes.
