## Watts to dBm conversion

### Watts to dBm conversion

This conversion calculator is used to convert the power in Watts (W) to power in a decibel-milliwatts (dBm). It gives quick and accurate results based on the input values. First, use the blank text field to enter the value in Watts. Press the ‘Convert’ button to initiate the conversion from Watts to dBm. The result is displayed below the controls in decibel-milliwatts. If you want to perform new conversions, use the ‘Reset’ button to erase all data of previous calculations from the converter.

##### Example;

Convert 350 Watts to dBm

##### Solution

The first procedure is to enter the value in Watts (350) in the blank text field. Click the ‘Convert’ button to get the results in dBm as;

350 Watts = 55.440680444 decibels-milliwatts

This means that there are 55.440680444 decibel-milliwatts in 350 Watts.

Use the same procedure when converting new values in Watts to get the corresponding results in decibel-milliwatts.

The ‘Reset’ button enhances the flexibility of the Watts to dBm converter as it can only perform one conversion at a time.

#### How to convert Watts to dBm?

P(dBm) = 10 ⋅ log_{10 }(1000 ⋅ P(W) / 1W)

P(dBm) = 10 ⋅ log_{10 }(P(W) / 1W) + 30

The power in decibel-milliwatts is calculated by 10 multiplied by the base 10 logarithms of 1000, times the power in watts. The result is then divided by 1 Watt.

Therefore;

1 Watt = 30 decibel-milliwatts

There are 30 decibel-milliwatts in a watt. If you want to determine the number of decibel milliwatts in a watt, multiply 10 by the base logarithm of 1000 times the power in watts.

For example;

Convert 45 watts to dBm

Solution

P(dBm) = 10 ⋅ log_{10 }(1000 ⋅ 45 W / 1W)

= 46.532125138 decibel-milliwatts in 45 watts.

The Watt to dBm conversion table is used in the conversion of common values from milliwatts to decibel-milliwatts on a scale of 0W to 1000000W.
