dBm to Watt Conversion

dBm (decibel-milliwatts) is used to indicate a power level in decibels with respect to 1 milliwatt. 0 dBm will be equivalent to 1 mW. 

Watt is the SI unit of power. It can also be defined as 1 joule per second.

It can also be defined as 1 joule per second. dBm to watt is calculated using the following formula

dBm, short for decibel-milliwatts, is a unit used to measure signal strength or power level, relative to 1 milliwatt. For instance, 0 dBm corresponds to 1 milliwatt. This unit is widely used in radio, microwave, audio, and fiber-optical communications networks. Expressing power in dBm offers the advantage of conveniently representing both large and small power values. For example, 5 mW is equivalent to 7 dBm, and 100 kW is equal to 80 dBm. Additionally, using the decibel unit simplifies multiplication and division operations into addition and subtraction.
