Okay kiddo, so imagine you have a big bag of toys that weighs a lot. Let's say it weighs 2,000 pounds. That's a really big number to remember, right?
Well, grown-ups use something called a "short ton" to talk about big weights like that. A short ton is just a fancy way of saying 2,000 pounds.
So instead of saying "my bag of toys weighs 2,000 pounds," a grown-up might say "my bag of toys weighs 1 short ton."
It's just a way to make talking about big weights a little bit easier!
