30 dBm converts to approximately 1 watt.
To convert from dBm to watts, use the formula: Watts = 10^((dBm – 30)/10). For 30 dBm, subtract 30 to get 0, then raise 10 to that power, resulting in 1 watt. This calculation shows that 30 dBm corresponds exactly to 1 watt of power.

Conversion Formula
The conversion from dbm to watts relies on the logarithmic relationship: Watts = 10^((dBm – 30)/10). This formula converts the logarithmic power level in decibels to a linear scale. It works because each 10 dB increase corresponds to a tenfold increase in power. For example, 30 dBm is 10^((30 – 30)/10) = 10^0 = 1 watt.
Conversion Example
- Convert 20 dBm to watts:
- Subtract 30 from 20: 20 – 30 = -10.
- Divide by 10: -10 / 10 = -1.
- Calculate 10^(-1): 0.1 watt.
- Convert 40 dBm to watts:
- Subtract 30: 40 – 30 = 10.
- Divide by 10: 10 / 10 = 1.
- Calculate 10^1: 10 watts.
- Convert 10 dBm to watts:
- Subtract 30: 10 – 30 = -20.
- Divide by 10: -20 / 10 = -2.
- Calculate 10^(-2): 0.01 watt.
