How This Converter Works
Converts decibel-milliwatts to milliwatts using the 1 mW reference power. Divide the dBm value by 10, then raise 10 to that power.
Formula or rule
mW = 10^(dBm / 10)
Example
- Input
- 20 dBm
- Calculation
- Divide by 10 and exponentiate: 10^(20 / 10) = 10^2 = 100.
- Result
- 100 mW
