Exactly, we also had this early on. Also with imperial measurements or some random antique ones. I remember the worst conversion exercises were in grade 5, where you had to convert a large number, say 5316, to a number if the base was 8, not 10. This felt completely useless and took a lot of time but it also wasn’t necessarily hard. And it made sense because math usually does.
Fuck me we did those conversions in primary school in Italy in the eighties. Can’t remember what year exactly but we were prolly 7yo?
