How the formula works
Both milliwatt and centiwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliwatts by 0.1 to get centiwatts. To reverse the conversion, multiply a centiwatt value by 10 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 Centiwatt (cW)?
A Centiwatt (cW) equals 1/100 watt(s), a scaled unit of electrical power used for centi-scale electrical work.
How do I convert milliwatts to centiwatts?
Multiply the milliwatt value by 0.1 to get the equivalent in centiwatts. For example, 5 mW × 0.1 = 0.5 cW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.1 is an exact, non-rounded value.
Can I convert centiwatts back to milliwatts?
Yes. Divide the centiwatt value by 0.1, or multiply it by 10, to get milliwatts.
