I just found out that a ton doesn't mean the same thing everywhere, and it's more confusing than I thought. In the U.S., they use one thing, in the U.K. another, and the rest of the world uses the metric system. Basically, there are three different versions of the same concept.

The American short ton is 2,000 pounds, the British long ton is 2,240 pounds, and the international metric ton is exactly 1,000 kg. It all comes from an old barrel used to transport wine on ships. Over time, it became a unit of weight, and each region adapted it to their own way.

In practice, this matters quite a bit. If an American company ships cargo to Europe and doesn't specify which ton they're using, they could end up with measurement disasters. That's why science always uses the metric system—to avoid confusion.

Today, it's used everywhere: mining, construction, shipping, even to measure carbon emissions. People even casually say "I have tons of work" to mean a lot. Ships have a cargo capacity measured in tons, and there's even a refrigeration unit based on tons of melting ice.

Meanwhile, the TON token continues its trend in the market, completely different but with a name that causes confusion haha. Did anyone else get surprised by this?
