How the formula works
Both microwatt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microwatts by 0.001 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 1000 to get back to microwatts.
Frequently asked questions
What is Microwatt (uW)?
A Microwatt (uW) equals 1e-06 watt(s), a scaled unit of electrical power used for micro-scale electrical work.
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.
How do I convert microwatts to milliwatts?
Multiply the microwatt value by 0.001 to get the equivalent in milliwatts. For example, 5 uW × 0.001 = 0.005 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert milliwatts back to microwatts?
Yes. Divide the milliwatt value by 0.001, or multiply it by 1000, to get microwatts.
