The conversion of 23 dBm to watts results in approximately 0.2 watts.
To convert dBm to watts, you use the formula: Watts = 10^((dBm – 30) / 10). This calculation transforms the logarithmic dBm value into a linear measure in watts, showing the actual power level. For example, at 23 dBm, the calculation is 10^((23 – 30)/10) = 10^(-0.7) ≈ 0.2 watts.

Conversion Formula
The conversion formula from dbm to watts is Watts = 10^((dBm – 30) / 10). It works because dbm is a logarithmic scale representing power levels, and this formula translates those levels into linear watts. For example, if dBm is 23, then:
- Subtract 30 from 23, getting -7.
- Divide -7 by 10, resulting in -0.7.
- Calculate 10 raised to the power of -0.7, which gives approximately 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.
