Decibel-milliwatts
A decibel milliwatt (dBm) is a unit of power level used in radio, microwave, and fiber-optic communication networks. It is a logarithmic unit that expresses power relative to one milliwatt.
Gigawatts
A gigawatt (GW) is equal to one billion watts. It is used to measure large-scale power output, such as the capacity of entire power grids or large power plants. Gigawatts are used in the context of national or regional energy production.
