dBW to dBm Conversion Calculator

The dBW to dBm calculator allows you to easily convert a power expressed in dBW into its corresponding value in dBm.
This tool is handy for RF engineers and technicians who work on signal transmission and measurement systems.

dBW

Formula used

dBm = dBW + 30

Explanation

The conversion between dBW and dBm is simple: simply add 30 to the dBW value to obtain the equivalent dBm value.
This formula is based on the difference in scale between the two units, where 1 dBW corresponds to 30 dBm.

Calculation example

For a power of 5 dBW :
dBm = 5 + 30 = 35 dBm

Benefits and Use

  • Quick conversion between dBW and dBm without manual calculation.
  • Useful for sizing and analysis of RF systems.
  • Allows you to easily compare power levels between different units.
  • Practical for laboratory or field measurements.
