deciwatt to milliwatt
Convert deciwatt (dW) to milliwatt (mW). Use an editable power converter, conversion formula, and reference table.
1 dW = 100 mW
Conversion formula
One deciwatt equals 100 milliwatt. Multiply your value in deciwatt by this factor to get milliwatt. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 deciwatt:5 × 100 = 500 mW

About these measurements
Power is the rate of energy transfer.
The base reference used here is the watt. One deciwatt is 0.1 base units; one milliwatt is 0.001 base units.
Important distinctions
Mechanical horsepower and metric horsepower are distinct units.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert dW to mW?
Multiply the quantity in dW by 100. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the milliwatt to deciwatt converter.
