The conversion of 23 dBm equals approximately 0.2009 watts.
To convert 23 dBm into watts, you use the formula that relates decibel-milliwatts to watts, which involves exponentiating 10 to the power of (dBm value divided by 10), then dividing by 1000. This process transforms the logarithmic dBm value into a linear watt measurement, making it easier to understand the actual power level.

Conversion Formula
The formula for converting dbm to watts is Watts = 10^ (dBm / 10) / 1000. It works because dBm is a logarithmic measurement of power relative to 1 milliwatt. By exponentiating 10 to the power of (dBm divided by 10), we revert from the logarithmic scale to a linear scale, then divide by 1000 to convert milliwatts to watts. For example, at 23 dBm: 10^(23/10) = 10^2.3 ≈ 199.526, then divide by 1000 gives about 0.199526 watts.
Conversion Example
- Convert 10 dBm:
- Calculate 10^(10/10) = 10^1 = 10
- Divide by 1000: 10 / 1000 = 0.01 watts
- Convert 0 dBm:
- Calculate 10^(0/10) = 10^0 = 1
- Divide by 1000: 1 / 1000 = 0.001 watts
- Convert 30 dBm:
- Calculate 10^(30/10) = 10^3 = 1000
- Divide by 1000: 1000 / 1000 = 1 watt
- Convert -10 dBm:
- Calculate 10^(-10/10) = 10^-1 = 0.1
- Divide by 1000: 0.1 / 1000 = 0.0001 watts
