I had a test yesterday. There was a question about fraction number and it's way of writing. What is the right form of spelling of "1/2 ton"? A half of ton, half of a ton or half a ton?


You can say either:

half a ton


one half ton

Without an "of" in "1/2 ton", you can't say "half of a ton". "half of ton" is wrong because "ton" requires an article.

  • It means I shouldn't put "of" between "half" and "ton"? – Yerkezhan Aug 15 '14 at 3:02
  • Not when you are directly writing or saying "1/2 ton". I added some additional detail to my answer. – user3169 Aug 15 '14 at 3:06
  • I disagree that you can't say "half of a ton" in fact I think that "half o' ton" is the shortened form of "half of a ton" – Jim Aug 15 '14 at 4:35
  • @Jim You can say it, but not as "1/2 ton" literally. – user3169 Aug 15 '14 at 4:37
  • Ok, yes,right, for the OP's purpose you'd never write out "1/2 ton" as "half of a ton" – Jim Aug 15 '14 at 6:14

It depends on the context. Normally, you would probably say "half a ton", as in

The ingot weighs half a ton.

However, if "1/2 ton" is an adjective, then you would write

You need a forklift to move that half-ton ingot.
