Use this calculator to convert dBm to Watt and Milliwatt.
dBm or decibel-milliwatts is an absolute unit of power measurement that’s referenced to one milliwatt.
dBm is often used in radio frequency (RF) and microwave engineering. Like the dB scale, it is convenient to use on account of the small number of digits used to represent large numbers. For instance,
- 30 dBm = 1 Watt
- 100 dBm = 10000000 Watt
- 150 dBm = 1000000000000 Watt
