> use feet worldwide, to be fair

Many CIS countries and China use metre flight levels[1] and kilometres per hour for indicated speed reporting. Additionally, the ICAO has recommended transiting to metre flight levels since 1979[2]. More additionally, the Airbus A300 had flight levels initially set up to be metric (obviously, since it was an effort spearheaded by the French), but to appeal to American airlines the Airbus consortium switched to feet. Although I am positive that Airbus engineers work exclusively in SI.

METARs worldwide except in North America use SI units for reporting weather.

No, and this is not an aircraft, is it?

TV screens and monitors are also measured in inches. ¯\_(ツ)_/¯

		They are decidedly not. They are marketed in inches of the diagonal (a supremely brain-dead decision, if you ask me), but they are engineered, manufactured, and even programmed only in SI units. If you look at your display's EDID output, the diagonal doesn't even factor in; what you do have are vertical, horizontal, and per-pixel dimensions; all in millimetres. This is what all panel manufacturers (LG, AUO, Samsung, Innolux, BOE, TCL, and so on) do.

		In Germany you have to always mention the metric size. Luckily.
