How to use this Decibel-milliwatts to Watts Converter 🤔
Follow these steps to convert given power from the units of Decibel-milliwatts to the units of Watts.
Enter the input Decibel-milliwatts value in the text field.
The calculator converts the given Decibel-milliwatts into Watts in realtime ⌚ using the conversion formula, and displays under the Watts label. You do not need to click any button. If the input changes, Watts value is re-calculated, just like that.
You may copy the resulting 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 Watts is:
Substitute given Power(Decibel-milliwatts) = 20 in the above formula.
Power(Watts) = Math.pow(10,(20/10)) / 1e3
Power(Watts) = 0.1
Therefore, 20 dBm is equal to 0.1 W.

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.
Watts
The watt (W) is the SI unit of power, defined as one joule per second. It is used to measure the rate of energy transfer and is commonly used in a wide range of applications, including electricity, mechanics, and heating.
