How do I convert minutes to decimal hours for a timesheet?
Divide the minutes by 60. 45 minutes is 0.75 hours, so 7 hours 45 minutes is 7.75 hours. The calculator shows this for every result.
What about night shifts?
In Hours between times, an end time earlier than the start time counts as the next day. 22:00 to 06:00 is 8 hours.
