1. 0.9 meters
  2. 1.0 meters
  3. 1.1 meters

I thought if we want to use the plural, the number of the noun should be 2 or more than 2.

So Why should*"0.9 meters" and "1.0 meters"* use "meters " not "meter"?


You use the plural when the number is not 1, and not a fraction with numerator 1. So you say "one quarter meter" and "0.25 meters".

For fractions with larger numerators, you would generally say "two thirds of a meter". You should do the same thing for fractions with numerator 1 which aren't common: "one seventeenth of a meter". (What does "common" mean? Certainly 1/2, 1/3, 1/4, 1/10, and probably a few more. You can use the "of a" form for common fractions as well.)

  • What about "1.0 meaters"? I thought 1.0 is equal to 1, so it should be “1.0 meter”. – user48070 Nov 8 '13 at 2:21
  • Both "two thirds meters" and "two thirds meter" sound very wrong to me. I agree with your suggested two thirds of a meter, and you're correct about using the singular when the number is 1, but... I can't get behind two thirds meter(s). – WendiKidd Nov 8 '13 at 3:24
  • I think both "1.0 meters" and "1.0 meter" work. – Peter Shor Nov 8 '13 at 8:45
  • Should we use plural or singular for a fraction of a mile? 1.0 may not exactly be one. – 243 Dec 2 '13 at 4:05
  • 1
    I would definitely prefer "a quarter of a meter" over "a quarter meter" and any other of your 'common fractions'; about the only time I wouldn't say "of a" is for half, and then I'd say "half a meter". – Hellion Dec 22 '13 at 1:29
