How to convert minutes to hours
Divide minutes by 60 to get decimal hours. For example, 90 minutes ÷ 60 = 1.5 hours, which is exactly 1 hour 30 minutes. A value such as 2 hours 30 minutes should be written as 2.5 decimal hours, not 2.30.
The calculator also returns an exact hours:minutes:seconds duration, so you can use whichever format your timesheet, schedule or calculation needs.
To add several hour-and-minute entries, use the hours calculator. To find elapsed time from a start and end clock reading, use the hours between two times calculator.
