When I was in the military in a leadership class, we had to use a protractor to calculate angles and distances on the map given a bunch of coordinates. I realized these were all right triangles, said fuck the protractor, and used trigonometry to get exact answers. I earned distinguished honor graduate, ie top of the class, despite my lab nerd POG ass being mixed in with a ton of infantry and ranger battalion guys.

I use dimensional analysis on a near daily basis because it’s just so damn handy. You can convert anything to nearly anything else as long as you have some numbers with the appropriate units in between.

Dimensional analysis needs to be taught way sooner (referring to USA education here). I'm sure I had some sense of it earlier, but it wasn't explicitly spelled out to me until college engineering courses. That's despite taking a significant number of AP and community college math and science courses in highschool. It seems like it should be part of middle school.
