How to use this Decibel-watts to Decibel-milliwatts Converter 🤔
Follow these steps to convert given power from the units of Decibel-watts to the units of Decibel-milliwatts.
Enter the input Decibel-watts value in the text field.
The calculator converts the given Decibel-watts into Decibel-milliwatts in realtime ⌚ using the conversion formula, and displays under the Decibel-milliwatts label. You do not need to click any button. If the input changes, Decibel-milliwatts value is re-calculated, just like that.
You may copy the resulting Decibel-milliwatts 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-watts to Decibel-milliwatts is:
Substitute given Power(Decibel-watts) = 40 in the above formula.
Power(Decibel-milliwatts) = 40 + 30
Power(Decibel-milliwatts) = 70
Therefore, 40 dBW is equal to 70 dBm.

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.
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.
