    Have you ever bought a ton of anything?

    Did you put it on the scales and make sure that it was exactly one million grams or go, “yh, that looks like it’s about a ton”.?

    That’s why the term ton is popular, the term megagram only really makes sense when you need your “ton” to be precisely one million grams.

      Beg to differ. That’s kind of an imperial measurement system way of thinking about units. But there’s probably some truth to it.

      No. Tolerance is tolerance no matter what the unit is. There is implied tolerance but that’s also the same for “one A” and “one B” no matter what A and B are.

        If you bought a ton of coal and the tolerance was ±5Kg who’s scales are you using when it gets delivered to your house?

        Or are you looking at size of the bag and thinking, yep, looks like a ton.
