A lot of these are more to do with age or products imported from the US than anything. For example with the temperature one, I would never give the temperature of anything in f, but my parents’ hot tub only displays temperature in f. Also my parents follow a flowchart like this much more than I do because they grew up with a more mixed system. Like they will sometimes give distance in miles whereas I would only ever in km. However there are some of these that even I do. Like I would only ever give my height and weight on feet, inches, and pounds.
