This is in relation to the question "It's “1 degrees” or is it “1 degree” outside?". I have heard many people say that it is zero degrees outside. Is this correct, or is it 0 degree? The latter simply doesn't sound right.

"One degree" is correct, as is "zero degrees". It grates on my inner geek that a quantity of zero is pluralized, but that's the way it is.

    @Janus: everything except "one half" or "a half", but maybe that counts as a singular half-mile. "One half mile", but "0.5 miles". – Peter Shor Jan 03 '14 at 18:43
  • Indeed, it's one half-mile, or one-half of a mile. Either way, it's a single mile that's being halved; hence the singular usage. – DopeGhoti Jan 03 '14 at 18:56
  • But that applies to all fractions, not just one half: two-thirds of a mile, three-quarters of an hour. – aeismail Jan 03 '14 at 19:35
  • @aeismall it is one third of a mile, two thirds of a mile, one quarter of an hour, three quarters of an hour. – emory Jan 03 '14 at 19:40

    @Peter, ‘half’ when used like that basically functions like an adjective, so even though the semantic meaning of the mile changes, it is still a singular. You can also speak of a double mile, which is the same as two miles, but it is grammatically singular. Only numerals (including decimals) and determiners can force a noun to non-singularity; adjectives do not (vel sim). – Janus Bahs Jacquet Jan 03 '14 at 20:05
  • Let's not forget -1 degrees. – Jeremy Jan 03 '14 at 20:38
  • Let's do; it'd be "negative one degree", or "one degree below zero", or (if you want to make peoples' eyes twitch) "minus one degree". – DopeGhoti Jan 03 '14 at 20:43

    If 0 degrees offends, just use 273 Kelvin. For similarly geeky reasons there are no degrees Kelvin – mgb Jan 04 '14 at 01:02
