How the formula works
Both milliwatt and microwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliwatts by 1000 to get microwatts. To reverse the conversion, multiply a microwatt value by 0.001 to get back to milliwatts.
Frequently asked questions
What is Milliwatt (mW)?
A Milliwatt (mW) equals 1/1,000 watt(s), a scaled unit of electrical power used for milli-scale electrical work.
What is Microwatt (uW)?
A Microwatt (uW) equals 1e-06 watt(s), a scaled unit of electrical power used for micro-scale electrical work.
How do I convert milliwatts to microwatts?
Multiply the milliwatt value by 1000 to get the equivalent in microwatts. For example, 5 mW × 1000 = 5000 uW.
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 microwatts back to milliwatts?
Yes. Divide the microwatt value by 1000, or multiply it by 0.001, to get milliwatts.
