Don't be mean. I promise to do my best to judge that fairly.

Rankine is used in chemical engineering calcs because a lot of US chemical plants are built in US Customary units and it's a lot easier to calculate in Rankine and keep everything in that system than try to convert back and forth between K and F.
Thanks for the interesting info! I figured it was used somewhere, just hadn't seen it.
And reminded me of the unit I saw once that I hate the most. Kilofeet... Not kidding. Apparently used in telecommunications as a unit of length for spools of cable, probably for similar reasons of easier math but couldn't fully switch from the US standard.
Lmao that too. We use kilopounds as well because tons are too easily confused with metric tons
