I'll start. Fahrenheit is the superior temperature system for weather reporting. We should use metric for literally everything else, even Celsius for cooking, but I'll be dead in the cold ground before I abandon a system in which you actually get to experience both 0 degrees and 100 degrees. Freezing being 32 instead of 0 is literally the only downside, and it's not a hard number to remember. I'm prepared to die on this hill in the comments.
you could do the horrific thing we do here and keep both
Good luck getting Americans to use Celsius lol. We can't even adopt the objectively superior meters and kilograms
my measurement brain is a mess lol
I think of distance in both miles and kilometres
but think of speed in miles per hour unless it's very fast, then it's metres per second
I think of length in both centimetres and inches
but height in only feet and inches
I think of weight of people in stone
but weight of literally everything else in metric
I think of liquid volume in purely metric
except fuel efficiency I think of in miles/gallon
England is fun
