Singular or plural for seconds

For numbers of seconds, is it smaller or equal to 1 we use second, larger than 1 we use seconds?

For example:

0 second
0.5 second
1 second
1.5 seconds


SOME of the rules around 1 are:

  • “X somethings” when X is not 1

  • For 1 and 0 amounts with decimals pronounced “0 point Y” and “1 point Y”, it is somethings:
    0.5 somethings, 0.1 somethings, 1.5 somethings, 1.1 somethings

  • For quantifications ending on a something, we have half a something, a quarter of a something because it is still relative to 1 (or a)

The same is the case for time, weight, money and other quantifications.

  • 1 second/kilo/dollar
  • half a second/kilo/dollar
  • a third of a second/kilo/dollar
  • a quarter of a second/kilo/dollar – note a quarter (dollar) is one coin in the US.

  • 0 seconds/kilos/dollars

  • 0.5 (zero point five) seconds/kilos/dollars
  • 0.1 (zero point one) seconds/kilos/dollars

For the rest of the rules and exceptions and possibly perceived rules, have a read of the answers to Is -1 singular or plural?
