How the formula works
Both centiwatt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiwatts by 10 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 0.1 to get back to centiwatts.
Frequently asked questions
What is Centiwatt (cW)?
A Centiwatt (cW) equals 1/100 watt(s), a scaled unit of electrical power used for centi-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 centiwatts to milliwatts?
Multiply the centiwatt value by 10 to get the equivalent in milliwatts. For example, 5 cW × 10 = 50 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 10 is an exact, non-rounded value.
Can I convert milliwatts back to centiwatts?
Yes. Divide the milliwatt value by 10, or multiply it by 0.1, to get centiwatts.
