1.5 hours are "One hour and half" or "One and half hours"?

Examples:

He will be there in 1.5 hours.

I spend there 1.5 hours.

It's either "one and a half hours" (plural because it's more than one hour) or "one/an hour and a half".

  • Or "an hour and a half" (more common in relaxed speech). – Michael Harvey May 24 at 8:12
  • What about "an hour and half" (without "a")? I've seen it used a lot. – Jan May 24 at 8:58
  • @Jan-Re: "I've seen it used a lot", see here and pay attention to the date of usage. – VictorB May 24 at 9:25
