I just realized that there are three different types of tons, and honestly, I was surprised. I always thought a ton weighed the same everywhere, but it turns out that in the U.S. they use something called a short ton (2000 pounds), in the UK the long ton (2240 pounds), and the rest of the world uses the metric ton, which is 1000 kilograms. How much a ton weighs basically depends on where you are.

The strange thing is that this goes back centuries, when the British measured wine barrels, and that became a unit of weight for maritime trade. The Americans later changed the measurement according to their own regulations, and it has remained that way until today.

I was struck by the fact that this causes real problems. Imagine a company shipping cargo from the U.S. to Europe and not clearly specifying whether they’re talking about short tons or metric tons—that could cause a mess. That’s why scientists always use the metric system to avoid confusion.

Now I understand why when people say "I have tons of work," they actually mean a lot, it’s not literal haha. Has anyone else not known there were so many different versions?
