What this calculator does
Converts a measurement given in decibel-milliwatts into milliwatts using the defined conversion factor.
What your result means
The same quantity expressed in mW instead of dBm. Nothing about the measurement itself changes.
Formula and working
mW = convert(dBm) through W
- 1
Start with your value
10 dBm
- 2
Apply the unit relationship
mW = convert(dBm) through W
- 3
Result
10 dBm = 10 mW
Frequently asked questions
Symbols and assumptions
- dBm
- Input unit — decibel-milliwatt
- mW
- Output unit — milliwatt
- W
- Base unit used internally for power
- • Both units measure power, so the physical quantity is unchanged by the conversion.
- • The two units are related by a defined equation rather than a single multiplier, so that equation is applied directly.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.

- • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
- • Displayed figures are rounded for readability; the full stored precision of the mW value is used in every onward calculation.
