27 dBm equals approximately 0.5012 watts.
To convert 27 dBm to watts, you use the formula that relates decibel-milliwatts to watts: watts = 10^((dBm – 30)/10). Plugging in 27 dBm, the calculation becomes 10^((27 – 30)/10) = 10^(-0.3) which results in about 0.5012 watts.
Conversion Result
Converting 27 dBm gives roughly 0.5012 watts. This shows how power levels expressed in decibel-milliwatts can be translated into watts, a standard unit of power measurement in electrical systems.

Conversion Formula
The conversion from dbm to watts uses the formula: watts = 10^((dBm – 30)/10). This works because dBm is a logarithmic measurement of power relative to 1 milliwatt. By subtracting 30, we adjust the scale from milliwatts to watts, then exponentiate to find actual power.
For example, with 27 dBm: (27 – 30) / 10 = -0.3. Then 10^(-0.3) ≈ 0.5012 watts, showing the power level in watts corresponding to 27 dBm.
Conversion Example
- Convert 20 dBm to watts:
- (20 – 30) / 10 = -1
- 10^(-1) = 0.1 watts
- Convert 0 dBm to watts:
- (0 – 30) / 10 = -3
- 10^(-3) = 0.001 watts
- Convert 50 dBm to watts:
- (50 – 30) / 10 = 2
- 10^2 = 100 watts
- Convert 10 dBm to watts:
- (10 – 30) / 10 = -2
- 10^(-2) = 0.01 watts
- Convert 30 dBm to watts:
- (30 – 30) / 10 = 0
- 10^0 = 1 watt

Conversion Definitions
dbm is a logarithmic measure of power relative to 1 milliwatt. It indicates how much power a device outputs or receives compared to 1mW, making it easier to compare very small or large power levels in communication systems.
Watts is a standard unit of power representing the rate at which energy is transferred or converted. It is used across electrical and mechanical systems to quantify energy flow, with 1 watt equaling 1 joule per second.
