dBm Converter

The decibel-milliwatts (dBm) converter is used to convert decibel-milliwatts to milliwatts, watts, and decibel-watts. It has four blank text fields and control buttons. The ‘Convert' button at the end of each blank field are used to initiate the conversion from one unit to give you the result of the other units. If you want to change a value or perform a new calculation then you will use the ‘Reset' button. It is the fastest way of adjusting the calculator as it erases all previous data with a single click.

For example,

Convert 0.2 decibel-milliwatts to milliwatts, watts and decibel watts.

Solution

The first procedure of using the calculator is to enter the value of decibel-milliwatts in its respective text field. Click the ‘Convert' button to execute the conversion. The results of other units will be displayed automatically as;

Milliwatts: 1.047129 mW

Watts: 0.001047 W

Decibel-milliwatts: 0.2 dBm

Decibel-watts: -29.8 dBW

The same procedure can be used when you want to perform new calculations.

Formula for conversion

How to convert dBm to mW

P (mW) = 1mW x 10 (P (dBm) / 10). Where, the power in milliwatts is equivalent to 10 raised by the power in dBm and then divided by 10.

How to convert dBm to Watt

P (W) = 1W x 10((P (dBm) - 30) / 10). It implies that the power in watts is equivalent to 10 raised by the power in dBm and then divided by 10.

How to convert dBm to dBW

P (dBW) = P (dBm) – 30. Where, the power in dBW is equivalent to 10 raised by the power in dBm and then divided by 10.

The dBm to Watt, mW, and dBW conversion table is also useful when determining the common conversions from decibel-watts to watts, milliwatts, and decibel-watts based on a scale of -100dBm to 100dBm.
