Frequently asked questions
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
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 watts to centiwatts?
Multiply the watt value by 100 to get the equivalent in centiwatts. For example, 5 W × 100 = 500 cW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 100 is an exact, non-rounded value.
Can I convert centiwatts back to watts?
Yes. Divide the centiwatt value by 100, or multiply it by 0.01, to get watts.
