In practice, decibels (dB), or tenths of a bel, are often used instead out of sheer convenience.
If you amplify a signal by a factor of 100, then you can write that as 20 dB of gain since 100 = 10².
In the resistor example earlier, the two resistors cause you to lose 12.5 dB and 30 dB of power each, for a total loss of 42.5 dB.
