23 dBm is approximately 0.2 Watts. This conversion helps understand the power level in practical terms.
To convert 23 dBm to watts, we use the formula: Watts = 10^((dBm – 30) / 10). Substituting 23 dBm gives us Watts = 10^((23 – 30)/10) = 10^(-0.7) which equals about 0.2 watts. This shows how the logarithmic dBm value relates to a linear power measurement.

Conversion Formula
The formula to convert dbm to watts is Watts = 10^((dBm – 30)/10). It works because dBm is a logarithmic measure of power relative to 1 milliwatt (mW). By subtracting 30, we adjust for the 1000-milliwatt scale, then raise 10 to that power to find the watt value. For example, for 23 dBm:
- Subtract 30: 23 – 30 = -7
- Divide by 10: -7 / 10 = -0.7
- Raise 10 to this power: 10^-0.7 ≈ 0.2 watts
Conversion Example
- Convert 10 dBm:
- Subtract 30: 10 – 30 = -20
- Divide by 10: -20 / 10 = -2
- Calculate 10^-2 = 0.01 watts
- Convert 0 dBm:
- Subtract 30: 0 – 30 = -30
- Divide by 10: -30 / 10 = -3
- Calculate 10^-3 = 0.001 watts
- Convert 50 dBm:
- Subtract 30: 50 – 30 = 20
- Divide by 10: 20 / 10 = 2
- Calculate 10^2 = 100 watts
