Are there any commonly used measurements, other than hectare and hectopascal, that use the prefix hect?

HectoPascal?

Pascals may come without a prefix, or in kilos, Megas or Gigas. I suppose some people might have a use for millis, but why would anyone want to use a hectoPascal?

Hectopascal has been the most commonly used barometric pressure unit by public-facing meteorologists in this country since I was a child. I’ve not heard anything else used in that context.

I suspect the reason it was chosen because it is close to the old millibar unit that SenCits may be more familiar with.

Haven’t you noticed that your tyre pressure recommendations are no longer in psi?
