## dBm to Watts Converter

### dBm to Watts Conversion

It is a conversion calculator that is used to convert the power in decibel-milliwatts (dBm) to Watts (W). It uses a simple formula and programmed controls to execute the conversions. Use the blank text field to enter the power in decibel-milliwatts. Click the ‘Convert’ button to execute the conversion from decibel-milliwatts to watts.

The results in watts will be displayed at the bottom panel of the calculator below the two controls. Use the ‘Reset’ button if you want to perform new calculations.This calculator gives accurate results depending on the values you enter in the blank text field.

##### For example;

Convert 0.15 decibel-milliwatts to watts.

##### Solution

The first step is to enter the value in decibel-milliwatts (0.15) in the blank text field. Click the ‘Convert’ button to get the results in Watts. It will be shown as; 0.0010351421667 W.

You can also repeat the same procedure using new values. Since the calculator can only perform one conversion at a time, you will have to use the ‘Reset’ button to clear the previous calculations. It gives a new space so that you can perform more conversions.

#### Formula for converting dBm to watts

P (W) = 1 W x 10^{ (P (dBm) / 10)} / 1000 = 10 ((P (dBm) - 30) / 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 and the result is then divided by one thousand.

**Using the example above;**

Convert 0.15 decibel-milliwatts to watts,

The calculation will be;

1 W x 10^{ (0.15 dBm / 10)} / 1000

= 0.0010351421667 Watts

The dBm to watts conversion table can also be used to determine the conversion of common values from decibel-milliwatts to watts based on a scale of -30 dBm to 50 dBm.
