Decibel-Milliwatts to Milliwatts conversion

Decibel-Milliwatts (dBm) to Milliwatts (mW) conversion calculator and how to convert.

Enter the power in dBm press the Convert button:

How to convert dBm to Milliwatts:

1 dBm = 1.258925 mW

The power conversion of dBm to mW is given by the formula:

P(mW) = 1 mW * 10P(dBm) / 10)

Example:

Convert 13 dBm to milliwatts:

P(mW) = 10(13 dBm / 10) = 19.95 mW
