# Watts conversion

## “ Convert dBm ”

This is an online conversion tool for converting

RF power between dBm and watts. These two parameters express the same quantity with watts expressed in linear terms and dBm in log terms.

Working with RF devices such as antennas, transceivers, transmitters and receivers often requires converting between these units.

RF power can be most accurately measured by using an RF or microwave power meter after accounting for system losses from RF cables and connectors. Alternatively a spectrum analyser, diode detector, log detector or receiver with RSSI may be used.
