Should thousand kilograms are a ton be accepted too?
That's not grammatical in English. You need to say "a thousand", not just "thousand".
I thought 2,000 pounds is a ton
It said kilos, not pounds. Each kilogram is 2.2 pounds. I think you can do the rest of the math. ;)
American pounds. ;)
According to the Academy of the Hebrew language, in the context of the measuring method one should say טוֹנה instead of טון.
is referred to a musical tone.
Actually "A thousand kilograms is a tonne", tonne = metric ton.
...and in the non-metric world is confusion....
