RF and signal power is often quoted in dBm, a logarithmic unit referenced to one milliwatt, and this converter turns it into plain watts and back. Power in milliwatts equals ten raised to the dBm value divided by ten, so zero dBm is exactly one milliwatt, thirty dBm is one watt, and every three dBm roughly doubles the power. Enter a dBm figure to get the equivalent milliwatts and watts, or enter a power in watts to get the dBm value, which is handy when you read a Wi Fi transmit power, a radio output, or a receiver sensitivity spec. Because the scale is logarithmic, large power ranges compress into small numbers, which is exactly why engineers use it. The tool converts in both directions and shows all three units together. Enter your value and read the result instantly. Everything runs locally in your browser.
