How the formula works
Both deciwatt and watt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in deciwatts by 0.1 to get watts. To reverse the conversion, multiply a watt value by 10 to get back to deciwatts.
Frequently asked questions
What is Deciwatt (dW)?
A Deciwatt (dW) equals 1/10 watt(s), a scaled unit of electrical power used for deci-scale electrical work.
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
How do I convert deciwatts to watts?
Multiply the deciwatt value by 0.1 to get the equivalent in watts. For example, 5 dW × 0.1 = 0.5 W.
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 watts back to deciwatts?
Yes. Divide the watt value by 0.1, or multiply it by 10, to get deciwatts.
