How this is worked out
Minutes are divided by 60 and added to the hours, which is the format most timesheets and payroll systems expect.
Worked example
- 7 hours
- 30 minutes
30 ÷ 60 = 0.5, added to 7
7.5 decimal hours, or 450 minutes
Assumptions and limits
- Minutes must be from 0 to 59. Entering 60 or more returns no answer rather than rolling over.
- Decimal hours are rounded to two places, so odd minute values are shown to the nearest hundredth of an hour.
