Samantha Nicole10 dBm equals approximately 0.01 W.
To convert 10 dBm to watts, we use the formula that relates decibel-milliwatts to watts, which is: W = 10^((dBm – 30) / 10). Substituting 10 dBm into this formula gives us the value in watts. This conversion helps understand the power level in a more practical unit.
Understanding the Conversion from dBm to Watts
The conversion from dBm to watts is based on the logarithmic scale used to measure power levels. The formula W = 10^((dBm – 30) / 10) converts the decibel-milliwatts into a linear power measurement in watts. For example, 10 dBm is calculated as 10^((10 – 30) / 10) = 10^(-2) = 0.01 W. It allows for comparing power levels in different units, especially in wireless communications and RF applications.

Conversion Formula
The formula W = 10^((dBm – 30) / 10) is derived from the logarithmic relationship between power in decibel-milliwatts and watts. It calculates the linear power by exponentiating 10 to the power of the adjusted dBm value divided by 10. For example, for 20 dBm, it becomes 10^((20 – 30)/10) = 10^(-1) = 0.1 W. This method gives accurate wattage from logarithmic units.
Conversion Example
- Convert 5 dBm to watts:
- Subtract 30 from 5: 5 – 30 = -25
- Divide by 10: -25 / 10 = -2.5
- Calculate 10 to the power of -2.5: 10^-2.5 ≈ 0.0032 W
- Convert 15 dBm to watts:
- 15 – 30 = -15
- -15 / 10 = -1.5
- 10^-1.5 ≈ 0.0316 W
- Convert 0 dBm to watts:
- 0 – 30 = -30
- -30 / 10 = -3
- 10^-3 = 0.001 W
- Convert 25 dBm to watts:
- 25 – 30 = -5
- -5 / 10 = -0.5
- 10^-0.5 ≈ 0.3162 W
- Convert -10 dBm to watts:
- -10 – 30 = -40
- -40 / 10 = -4
- 10^-4 = 0.0001 W
