Minutes to Hours Converter

How it works

One hour is 60 minutes, so to turn a number of minutes into hours you divide by 60:

hours = minutes ÷ 60

That gives the decimal hours — useful for timesheets and pay, where 90 minutes is 1.5 hours. To read the same duration as hours and minutes, take the whole number of hours and keep the remainder as minutes:

whole hours = ⌊minutes ÷ 60⌋ and remaining minutes = minutes − whole hours × 60

So 90 minutes is 1 whole hour with 30 minutes left over — 1 hour 30 minutes. The two forms describe the same length of time; decimal hours are handy for arithmetic, while hours-and-minutes match a clock.

Worked example

90 minutes is 90 ÷ 60 = 1.5 hours, or 1 hour 30 minutes. An 8-hour shift is 480 minutes, and 15 minutes is 15 ÷ 60 = 0.25 hours — a quarter of an hour.

Frequently asked questions

How do I convert minutes to hours?

Divide the number of minutes by 60, since an hour has 60 minutes: hours = minutes ÷ 60. For example, 90 minutes ÷ 60 = 1.5 hours. To express it as hours and minutes, that is 1 hour and 30 minutes.

How many hours is 90 minutes?

90 minutes is 1.5 hours, because 90 ÷ 60 = 1.5. As a clock reading that is 1 hour and 30 minutes — one full hour of 60 minutes plus a remaining 30 minutes.

What is the difference between decimal hours and hours and minutes?

Decimal hours express the whole duration as one number — 1.5 hours — which is convenient for pay and arithmetic. Hours and minutes split it into whole hours and leftover minutes — 1 hour 30 minutes — which matches how a clock reads. Both describe the same duration.

How do I convert 45 minutes to hours?

Divide by 60: 45 ÷ 60 = 0.75 hours, which is three-quarters of an hour. Common fractions are 15 minutes = 0.25 h, 30 minutes = 0.5 h and 45 minutes = 0.75 h.

How do I turn decimal hours back into minutes?

Multiply the decimal hours by 60. For example, 1.5 hours × 60 = 90 minutes, and 0.25 hours × 60 = 15 minutes. It is the reverse of dividing minutes by 60.

How many hours is 100 minutes?

100 minutes is 100 ÷ 60 = 1.667 hours, or 1 hour and 40 minutes. Because 100 is not a whole multiple of 60, the decimal form is a repeating 1.6666…, which rounds to about 1.67 hours.
