Phooey. I thought this might have something to do with "the three sizes." Haven't gotten rid of all the vestiges of my former teenage brain, I guess.

The problem with tons and tonnes is that one is imperial and the other is metric and they aren't the same. A metric tonne is 1000kg. I looked up the imperial ton and it is 2240 pounds ('cos that's a sensible number).
Wait, what? A ton is 2000 pounds.
*checks*
Huh. I had no idea an American imperial ton and an English imperial ton were different.

Metrics, all the way.
While I lived in US for a while, I eventually got used to all the alternative measures (although some are pretty counter-intuitive); but there was one I could never, ever, get used to: Fahrenheit. What kind of backward measure is that which sets the reference points at 32 and 212? Who measures something in 1/180th of an interval? I swear, after years, its bonkers to me...
According to Wikipedia, it's because the guys who came up with it used the freezing point of brine as the reference for 0 degrees, and the others followed from there before settling on the 32-212 1/180 interval thing. It doesn't say how they arrived at the
original number for the freezing point of water, but after they did, they just tweaked the degree separation to make the math easier. I actually never knew that before.
Honestly, though, I know Celsius is easier to comprehend, but I like how Farenheit is more precise without needing decimals.
