dBm to Watts Calculator
This free online tool converts dBm (decibel-milliwatts) to power in watts. It’s widely used in electronics, RF communication, audio engineering, and networking.
Formula Used: P(watts) = 10^((dBm - 30) / 10)
How to Convert dBm to Watts?
dBm is a logarithmic unit that expresses power relative to 1 milliwatt. To convert dBm to watts, use the formula P(W) = 10^((dBm - 30) / 10). For example, 30 dBm = 1 watt.
Common Conversions
- 0 dBm = 1 mW = 0.001 W
- 10 dBm = 10 mW = 0.01 W
- 20 dBm = 100 mW = 0.1 W
- 30 dBm = 1 W
- 40 dBm = 10 W
