The conversion of 35 dBm to watts results in approximately 3.16 watts.
To convert from dBm to watts, you use the formula: watts = 10^((dBm – 30) / 10). This means subtract 30 from the dBm value, divide by 10, then raise 10 to that power. For 35 dBm, subtract 30 to get 5, divide by 10 for 0.5, then 10^0.5 equals about 3.16 watts.
Understanding the Conversion
The formula to convert dBm to watts is watts = 10^((dBm – 30) / 10). This arises because dBm is logarithmic, representing power levels relative to 1 milliwatt. By subtracting 30, you shift from decibel-milliwatts to decibels relative to 1 watt, then exponentiate to find the actual wattage. For example, for 35 dBm:
- Subtract 30 from 35: 35 – 30 = 5
- Divide by 10: 5 / 10 = 0.5
- Calculate 10^0.5: approximately 3.16 watts.

Conversion Formula
The mathematical formula to convert dBm to watts is watts = 10^((dBm – 30) / 10). This is based on the logarithmic nature of dBm, which measures power relative to 1 milliwatt. The subtraction of 30 adjusts the scale to watts, and raising 10 to this power gives the wattage. For example, for 35 dBm:
- Subtract 30 from 35: 5
- Divide by 10: 0.5
- Calculate 10^0.5: about 3.16 watts.
Conversion Example
- Convert 50 dBm to watts:
- 50 – 30 = 20
- 20 / 10 = 2
- 10^2 = 100 watts
- Convert 20 dBm to watts:
- 20 – 30 = -10
- -10 / 10 = -1
- 10^-1 = 0.1 watts
- Convert 0 dBm to watts:
- 0 – 30 = -30
- -30 / 10 = -3
- 10^-3 = 0.001 watts
- Convert 60 dBm to watts:
- 60 – 30 = 30
- 30 / 10 = 3
- 10^3 = 1000 watts
