This one is for you, @hotdogsladies.

FAQ:
1) This is a proof-of-concept; no promises
2) I don't know when it'll ship, if I can even get it production-ready
3) Data coverage (Wikidata) is okay but not stellar; not all actors will have their heights shown
4) I'll try to use sensible units for countries that aren't idiots like us

I think I've got units working for countries that make sense.

This is all based on your setting in Settings โ†’ General โ†’ Language & Region โ†’ Measurement System.

๐Ÿ‡บ๐Ÿ‡ธ/๐Ÿ‡ฌ๐Ÿ‡ง get feet/inches.
The rest of the world gets cm.

I genuinely don't know how this will play in ๐Ÿ‡จ๐Ÿ‡ฆ, so, uh, good luck, northern friends? ๐Ÿ˜ฌ

@caseyliss we use centimetres in the uk, Casey. Please donโ€™t encourage the fascists from imposing Imperial measures. This is a thing they are doing.

(Shout out to all the Neoplatonist metrologists who know how to use inches, feet, various miles, and degrees, to engage in a humanistic, early antiquity world view.)

@grievousangel Tell Apple; their code specifies feet/inches.
@caseyliss gosh. The uk adopted the metric system in 1965.
@grievousangel based on anecdata it sounds like for peopleโ€™s heights specifically, the generally accepted unit is feet/inches
