it is the power ratio in decibels



No, it isn't. dB on its own is a ratio.

But when dB has a suffix, the figure is an absolute measurement, not a ratio.

For instance, dBm is a measurement of power compared to 1mW.

0dBm means zero difference between 1mW and the measured figure. In other words the measured figure is also 1mW.

3dBm is 3dB greater than 1mW. -3dB is 3dB less than 1mW. etc.

Another suffix is W. 0dBW being 1 watt.

There are many more suffixes, some of which are used in only a few specialised cases.
