What's a "metric ton" as mentioned in this article?


A metric ton is 1000 kilograms. *It equals 2205 pounds.

This is not the same as the English ton (aka long ton), which is 2240
pounds. And of course, it is not the same as the American/Canadian ton
(aka short ton) of 2000 pounds.


The "metric ton" is also sometimes called the "tonne". But I'm
surprised that it never seems to be called what it is: a megagram.
People seeing _that_ name would immediately know the value of the
unit.
