Why & how do people measure ‘how big’ a thing is by saying “X is (Y) pounds” are there any mathematical relation to it?
In: Mathematics
If you’re comparing two things that are generally really similar in structure, weight is a metric you can use that, while being really general, is a bit independent of other factors.
I can say my dog weighs 15 pounds, but that doesn’t really say anything about how tall it is or anything. That may or may not actually be relevant though, if “15 pounds” is good enough. If I compare it to someone’s 3 pound chihuahua, you know it’s bigger and don’t really need to be told it’s longer or taller.
It’s not the most correct way to do it, but it gets the point across.
