Milliwatt (mW) to Decibel-milliwatts (dBm) Converter

When dealing with wireless systems, vendors often provide power measurements in different units. Some use milliwatts (mW) while others use decibel-milliwatts (dBm). This bidirectional converter makes it easy to work in either measurement unit.

Milliwatt (mW):

Decibel-milliwatts (dBm):

How to use: Enter a value in either field and click Convert. The tool will calculate both conversions simultaneously.
