What is dBm to Watts Conversion Calculator?
dBm to Watts conversion calculator converts the power value in dBm to Watts value. Watt (W) is a SI unit for measuring power, and dBm is a decibel unit for measuring power.
How to Calculate Power (in Watts) for a Given dBm?
The following formula is used to calculate the power value (in W) for a given dBm value.
dBm stands for decibel-milliwatts; it is a dimensionless unit used to define/measure signal strength (power level), with reference to 1 milliwatt. (i.e., the power level of 0dBm represents 1 milliwatt). The dBm is a convenient unit used in radio, microwave, audio applications, and fiber-optical communications networks to measure signal strength.
The benefit of expressing signal strength (power) in dBm is that we can express both very large and very small power values (W) using a convenient number. For example, 5 mW is equal to 7 dBm, and 100 KW is equal to 80 dBm. Also, the decibel unit representation simplifies multiplication and division operations into addition and subtraction.
