The value of 17 dBm converts to approximately 0.0501 watts.
Table of Contents
To convert 17 dBm to watts, we use the formula that relates decibel-milliwatts to watts: Watts = 10^((dBm – 30) / 10). Plugging in 17 dBm results in 10^((17 – 30)/10) = 10^(-1.3) ≈ 0.0501 watts, showing how power levels in dBm translate to actual wattage.
Conversion Result
17 dBm equals about 0.0501 watts.

Conversion Formula
The formula to convert dbm to watts is Watts = 10^((dBm – 30) / 10). It works because decibel-milliwatts measure power on a logarithmic scale. Subtracting 30 converts dBm into dBW, then raising 10 to that power gives watts. For example, 17 dBm: (17 – 30)/10 = -1.3, so watts = 10^(-1.3) ≈ 0.0501.
Conversion Example
- Convert 10 dBm to watts:
- Calculate (10 – 30)/10 = -2
- Result = 10^(-2) = 0.01 watts
- Convert 0 dBm:
- Calculate (0 – 30)/10 = -3
- Result = 10^(-3) = 0.001 watts
- Convert 25 dBm:
- Calculate (25 – 30)/10 = -0.5
- Result = 10^(-0.5) ≈ 0.3162 watts
- Convert -10 dBm:
- Calculate (-10 – 30)/10 = -4
- Result = 10^(-4) = 0.0001 watts
- Convert 40 dBm:
- Calculate (40 – 30)/10 = 1
- Result = 10^1 = 10 watts
