The conversion of 17 dBm equals approximately 0.05012 watts.
To convert dBm to watts, the formula used is watts = 10^((dBm – 30) / 10). This calculation transforms the logarithmic decibel measurement into a linear power value in watts. For 17 dBm, subtract 30, divide by 10, then raise 10 to that power to get the wattage.

Conversion Formula
The conversion from dbm to watts is based on the formula: watts = 10^((dBm – 30) / 10). This works because dBm is a logarithmic measure of power relative to 1 milliwatt (mW). Subtract 30 from the dBm value to shift from milliwatt to watt scale, then raise 10 to the power of the result. For example, 17 dBm: (17 – 30) / 10 = -1.3; 10^(-1.3) ≈ 0.05012 watts.
Conversion Example
- Convert 20 dBm:
- (20 – 30) / 10 = -1
- 10^(-1) = 0.1 watts
- Result: 0.1 watts
- Convert 0 dBm:
- (0 – 30) / 10 = -3
- 10^(-3) = 0.001 watts
- Result: 0.001 watts
- Convert 30 dBm:
- (30 – 30) / 10 = 0
- 10^0 = 1 watt
- Result: 1 watt
- Convert 10 dBm:
- (10 – 30) / 10 = -2
- 10^(-2) = 0.01 watts
- Result: 0.01 watts
