0.5 years or 0.5 year? is the letter "S" at the end necessary?

Question

also 1.5 year or 1.5 years????
or is it correct if i say "one and a half year" instead of "one and a half years"?

Answer 1

In the US, our culture generally refers to it as "One and a half years."

Below one, it gets a little murky. One would say "half a year", but you would say ".5 years."

If you're referring to it in decimal format, anything other than exactly one would be referred to in plural (with the "s"), because you're speaking in plural units of measurement, even if the unit of measurement is less than one whole.

If you're referring to it in fractional form, anything that's one or less would be referred to without the plural form (without the "s") because you're referring to "a fraction of a year."

Answer 2

0.5 = half. You wouldn't say "half a years ago" would you? Similarly anything more than one is plural so needs an "s".
One and a half years ago

Answer 3

0.5 years,
1.5 years,
one and a half years
these are the correct answers
i am 100% sure,
but if you call 0.5 half then you say half a year.
if you call 0.5 point five then you call it point five years

Answer 4

0.5 years
1.5 years
you can only use year if it is a 1

Answer 5

it is 0.5 years.....0.5 cannot be construed as a singular..so its 0.5 years...and its also 1.5 years..for the same reason...and one and a half years

Answer 6

The alphabet wasn't created specifically for the English language.

Answer 7

"Half a year" because you are talking about a singular YEAR.
"0.5 years" because you are talking about multiple (5) tenths of a year.

Answer 8

years. Year is a unit of time, just as hour is.

when you say one and a half, you have to say years.

Like, o.5 meters, not o.5 meter.

Answer 9

just do like microsoft and go 0.5 year(s) because you're too lazy to program it correctly.

Answer 10

its half year and one a half years
