How minutes convert to hours
There are 60 minutes in an hour, so to convert minutes to hours you divide by 60. For example 150 ÷ 60 = 2.5 hours, which reads as 2 h 30 min. The decimal form is handy for timesheets and pay.
Two answers come out of the same division because time is base 60 while money and timesheets are base 10. 150 ÷ 60 = 2.5 gives the decimal hours used for pay; taking the whole part (2) and multiplying the 0.5 remainder back by 60 gives the 30 minutes used for a schedule. Both describe the same duration.
How to use this calculator
Type the number of minutes and read the decimal hours plus the hours-and-minutes badge. Going the other way? Use the decimal hours to time calculator, or convert smaller units with the seconds to minutes calculator.
Worked example for a timesheet: a shift of 7 hours 45 minutes is 465 minutes, and 465 ÷ 60 = 7.75 hours. At £14 an hour that is £108.50 — whereas typing 7.45 into the pay column, a very common slip, would pay £104.30. Any minute value that is not a multiple of 6 produces a repeating decimal, so 20 minutes is 0.333 hours rather than 0.20.
Common conversions
30 min = 0.5 h, 45 min = 0.75 h, 90 min = 1.5 h, 120 min = 2 h. Each minute is about 0.0167 of an hour, so multiply minutes by that factor for a quick mental estimate.
More conversions worth remembering: 6 min = 0.1 h, 15 min = 0.25 h, 20 min = 0.333 h, 36 min = 0.6 h, 40 min = 0.667 h and 75 min = 1.25 h. Payroll systems normally round to the nearest quarter hour or to two decimals, so check which rule your employer uses before reconciling a total. For longer spans the hours to days calculator continues the chain, and the work hours calculator totals a whole week of shifts.
Frequently asked questions
- How many hours is 150 minutes?
- 150 minutes is 2.5 hours, which equals 2 hours and 30 minutes.
- How do I convert minutes to hours?
- Divide the number of minutes by 60. The whole part is hours and the remainder, divided by 60, is the decimal portion.
- What is 90 minutes in hours?
- 90 minutes is 1.5 hours, or 1 hour and 30 minutes.
- Why use decimal hours?
- Payroll and billing systems usually expect decimal hours rather than hours and minutes, so 2 h 30 min becomes 2.5.
- Why isn't 7 hours 30 minutes written as 7.30?
- Because decimal hours are hundredths, not minutes: 30 minutes is half an hour, so it is 7.5. Writing 7.30 would claim 7 hours and 18 minutes, and mixing the two notations is the most common source of payroll errors.
