>Same reason(s) we haven’t finished switching to the metric system.
You're not totally wrong but like the UK we (US) tend to use the metric system where it actually matters and use our variant of Imperial for everyday things which makes perfect sense for anyone who grew up with it. Aside from not having a well-developed intuitive sense for what Celsius means from a comfort perspective when traveling, I can pretty much use whatever local units are in use. (My only real limitation at home is that, aside from my scale, I have very little metric measuring gear so I have to convert.)
