dBm to mW Conversion

It is a conversion calculator that is used to convert the power in decibel milliwatts (dBm) to milliwatts (mW). It uses a simple formula and programmed controls when performing the conversions. First, enter the value in decibel-milliwatts in the blank text field. Click the ‘Convert' button to initiate the conversion from decibel-milliwatts to milliwatts.

The results in milliwatts will be displayed below the two controls at the bottom panel of the calculator. Use the ‘Reset' button when you want to perform new conversions from decibel-milliwatts to milliwatts. This calculator gives accurate results depending on the values entered in the blank text field.

For example;

Convert 3 decibel-milliwatts to milliwatts.


The first step is to enter the value in decibel-milliwatts (3) in the blank text field. Click the ‘Convert' button to get the results in milliwatts. It will be shown as; 1.995262315 mW.

The same procedure can be repeated when you have new values in decibel-milliwatts. The efficiency of this calculator is enhanced by the ‘Reset' button. It is used to erase all data of previous calculations from the calculator.

Formula for converting dBm to milliwatts

P (mW) = 1 W x 10 (P (dBm) / 10)

This means that the power conversion of decibel-milliwatts to watts is given by 10 raised to the power of decibel-milliwatts divided by 10.

Using the example above;

Convert 3 decibel-milliwatts to milliwatts,

The calculation will be;

1 W x 10 (3 dBm / 10)

= 1.995262315 milliwatts (mW)

The dBm to milliwatts conversion table can also be used to determine the conversion of common values from decibel-milliwatts to milliwatts based on a scale of -40 dBm to 50 dBm.

Note that this calculator can only convert values from decibel-milliwatts to milliwatts. If the values are in milliwatts, we recommend using the mW to dBm converter.
