Decimal hours = minutes ÷ 60. The second column is rounded to two decimals, as most payroll systems do; the third shows four decimals for minutes that do not divide evenly, such as 20 minutes = 0.3333 h.
FAQ
How do I write 7 hours 20 minutes in decimal?+
Convert only the minutes: 20 minutes is 0.33 hours, so 7 h 20 min is 7.33 hours.
Why does my timesheet round differently?+
Some employers round time to the nearest 5, 6 or 15 minutes before converting. Six-minute rounding gives tenths of an hour: 6 minutes = 0.1 h.
