What is 0 dBm

This page describes - what is 0 dBm and mentions links to dBm vs Watt and dBm vs dBW converters.

0 dBm equals power of 1 milliwatt or 0.001 Watt or -30dBW. Let us understand this using following equations.

Equation-1 : dBm = Log₁₀(Power in milliwatt)*10
Equation-2 : Power in milliwatt = 10 ^{(Power in dBm/10)}
Equation-3 : dBW = dBm - 30

These power units are interchangeably used by RF engineers for representation and convenient purpose. 0 dBm is often used as nominal power for most of the RF Transmitters as output power.
