How to use this Decibel-milliwatts to Gigawatts Converter 🤔
Follow these steps to convert given power from the units of Decibel-milliwatts to the units of Gigawatts.
Enter the input Decibel-milliwatts value in the text field.
The calculator converts the given Decibel-milliwatts into Gigawatts in realtime ⌚ using the conversion formula, and displays under the Gigawatts label. You do not need to click any button. If the input changes, Gigawatts value is re-calculated, just like that.
You may copy the resulting Gigawatts value using the Copy button.
You can also reset the input by clicking on Reset button present below the input field.
Formula
The formula to convert given power from Decibel-milliwatts to Gigawatts is:
Substitute given Power(Decibel-milliwatts) = 20 in the above formula.
Power(Gigawatts) = Math.pow(10,(20/10)) / 1e12
Power(Gigawatts) = 1e-10
Therefore, 20 dBm is equal to 1e-10 GW.

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.
