This converter allows you to transform a power expressed in dBm into its equivalent value in dBW . The tool is simple and fast, providing instant result for RF engineers and technicians who work with different power units.
Formula
dBW = dBm – 30
Explanation of the formula
Converting dBm to dBW is simply a matter of subtracting 30 from the dBm value. Indeed, 1 dBW corresponds to 1 watt, while 0 dBm corresponds to 1 milliwatt. This difference of 30 decibels reflects the factor 1000 between milliwatt and watt.
Uses
- Quickly compare power levels expressed in different units.
- Convert values for calculations in RF systems or gain and loss diagrams.
- Facilitate technical documentation and measurement reports.
- Assist in the design and evaluation of amplifiers, antennas and transmission systems.
