The conversion of 17 dBm equals approximately 50.12 watts.
To convert from dBm to watts, you take the dBm value, subtract 30, then raise 10 to that power divided by 10. This works because dBm measures power level relative to 1 milliwatt, and the formula translates that logarithmic value into a linear watts value.
Conversion Result
17 dBm is roughly 50.12 watts.

Conversion Formula
The formula to convert dbm to watts is: watts = 10^((dBm – 30) / 10). This works because each 10 dB increase corresponds to a tenfold increase in power. By subtracting 30, we shift from a logarithmic scale to a linear scale relative to 1 milliwatt. For example, 17 dBm becomes 10^((17-30)/10) = 10^(-1.3) ≈ 0.0501 watts.
Conversion Example
- Convert 10 dBm to watts:
- Subtract 30: 10 – 30 = -20
- Divide by 10: -20 / 10 = -2
- Calculate 10^(-2): 0.01 watts
- Convert 0 dBm to watts:
- Subtract 30: 0 – 30 = -30
- Divide by 10: -30 / 10 = -3
- Calculate 10^(-3): 0.001 watts
- Convert 25 dBm to watts:
- Subtract 30: 25 – 30 = -5
- Divide by 10: -5 / 10 = -0.5
- Calculate 10^(-0.5): approximately 0.3162 watts
