Re: We can't be having descriptive nomenclature.

Frequency and Hertz is another example of confusion.

Bad example: 'frequency' and 'hertz' are not synonyms: Nobody would ever say "That was an annoying high Hertz noise" or "Radio 4 is on 93.5 frequency". IOW frequency is a synonym for the general terms 'oscillation' or 'vibration' but Hz denotes a measured frequency, which is a much more precise statement.

Hertz replaced cycles/sec as the preferred term denoting a measurement of frequency 40-50 years ago during a sudden mania for naming derived scientific units by the names of related scientists. The changeover was confusing: when I started University we used cgs units. By the time I graduated, we'd moved first to MKS units and then to the current names. Apart from the Hertz (Hz) losing information because you have to know what a Hertz is a synonym for (cycles/second) which is annoying for units you seldom use, it is easier to write Hz than cps, cycles/sec or c/s and it gets even better when you're dealing with KHz , MHz or GHz.
