The conversion of 46 dBm to watts equals approximately 39.81 watts.
To convert from dBm to watts, the formula used is: watts = 10^((dBm – 30) / 10). For 46 dBm, subtract 30 to get 16, then raise 10 to that power, resulting in about 39.81 watts. This calculation shows how power levels in decibel-milliwatts relate to actual watt measurements, making it easier to understand signal strength.
What is the conversion from 46 dBm to watts?
The conversion from 46 dBm to watts involves transforming a logarithmic scale of power into a linear measurement. Since dBm is a logarithmic unit, each increase of 10 dBm reflects a tenfold increase in power. The formula adjusts for this by reversing the logarithmic process, giving you the actual wattage.

Conversion Formula
The formula to convert dBm to watts is watts = 10^((dBm – 30) / 10). It works because dBm expresses power level in logarithmic terms, meaning each 10 dBm increase is a tenfold power increase. By subtracting 30, we convert from decibels to a linear scale, then raise 10 to that power.
For example, with 46 dBm:
- Subtract 30 from 46, resulting in 16.
- Divide 16 by 10, getting 1.6.
- Calculate 10^1.6, which equals approximately 39.81 watts.
Conversion Example
Let’s convert 50 dBm to watts:
- Subtract 30 from 50: 50 – 30 = 20.
- Divide 20 by 10: 20 / 10 = 2.
- Calculate 10^2: 10^2 = 100 watts.
So, 50 dBm equals 100 watts.
