How to use this Decibel-milliwatts to Decibel-watts Converter 🤔
Follow these steps to convert given power from the units of Decibel-milliwatts to the units of Decibel-watts.
Enter the input Decibel-milliwatts value in the text field.
The calculator converts the given Decibel-milliwatts into Decibel-watts in realtime ⌚ using the conversion formula, and displays under the Decibel-watts label. You do not need to click any button. If the input changes, Decibel-watts value is re-calculated, just like that.
You may copy the resulting Decibel-watts 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 Decibel-watts is:
Substitute given Power(Decibel-milliwatts) = 20 in the above formula.
Power(Decibel-watts) = 20 - 30
Power(Decibel-watts) = -10
Therefore, 20 dBm is equal to -10 dBW.

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.
Decibel-watts
A decibel watt (dBW) is a unit of power level relative to one watt, expressed in decibels. It is commonly used in telecommunications and audio engineering to describe power levels in a logarithmic scale.
