this feels like such a basic 2nd grade math thing, but i just realized that:
5' = 150cm i.e A Short Person(tm)
6' = 180cm i.e A Tall Person(tm)
and because 4" = 10cm, i can quickly convert to metric (i.e conceptualize the height in my head) by remembering:
5'0" = 150cm
5'4" = 160cm
5'8" = 170cm
5'12" (6') = 180cm
amazing; incredible; i now finally have a cheat sheet and or some basic intuition for people's height expressed in ft'in"
@wolfgang Ooh, this'll be useful for us going the other way! :3
