Nitpick: Celsius is not an SI unit.

Answering the substantive point: it’d be nice if we switched to SI units (plus Celsius); personally my phone is already set to display those and I wish we’d join the rest of the world and do standard stuff. However, I think it’s extremely unlikely to ever happen. The deadlocked US political system makes it impossible to enact any reform on any topic that anyone can create controversy about, and that includes switching to international standard units.
