7 hours 30 minutes is 7.5 decimal hours, or 450 minutes in total. 7 hours 45 minutes is 7.75 hours and 465 minutes, not 7.45, because minutes are sixtieths of an hour rather than hundredths.
Total minutes are the whole hours multiplied by 60 plus the extra minutes. Dividing those total minutes by 60 gives the decimal hours, and both figures are shown so you can paste whichever one your system expects.
Extra minutes must be between 0 and 59; anything longer belongs in the hours field. A decimal hour is a base-10 value and must not be read back as clock minutes, and no payroll rounding rule is applied, so the figure is shown as it comes out of the division.
Enter whole hours and the remaining minutes from 0 to 59. The tool divides the minutes by 60, so 7 h 30 min is 7.5 decimal hours and 7 h 45 min is 7.75, not 7.45. Writing 7.45 on a timesheet would record 7 hours and 27 minutes and underpay 18 minutes. The total-minute figure is shown as well: 7 h 45 min is 465 minutes, which is convenient when a system asks for minutes.
Quarter hours convert cleanly: 15 minutes is 0.25, 30 minutes is 0.5 and 45 minutes is 0.75. Other minutes give repeating decimals. 20 minutes is one third of an hour, so 8 h 20 min is 8.33333333 hours on screen, and 59 minutes is 0.98333333. Payroll systems often round to two decimal places, turning 8.3333 into 8.33; over many shifts that rounding can add up, so check which precision your employer uses.
For a weekly total, add hours and minutes first, then convert once. 37 h 50 min is 2,270 minutes, or about 37.83 decimal hours; multiplying 37.83333333 by an hourly rate of 20 gives about 756.67. Converting each day to two decimals and adding afterwards can differ by a cent or two. To go from shift times to hours, use the Work Hours or Time Card Calculator first, then convert the result here if a decimal figure is required.
| Input | Result |
|---|---|
7 h 30 min | 7.5 · 450 min |
7 h 45 min | 7.75 · 465 min |
0 h 15 min | 0.25 · 15 min |
8 h 20 min | 8.33333333 · 500 min |
37 h 50 min | 37.83333333 · 2270 min |
0 h 59 min | 0.98333333 · 59 min |
No. 45 minutes is 0.75 of an hour, so the correct value is 7.75. Writing 7.45 on a timesheet records 7 hours and 27 minutes and loses 18 minutes of pay. The quarter hours are the easy ones to remember: 15 minutes is 0.25, 30 minutes is 0.5 and 45 minutes is 0.75.
Because most minute counts are not a whole number of hundredths. 20 minutes is a third of an hour, so 8 h 20 min shows as 8.33333333 hours, and 59 minutes is 0.98333333. Payroll systems usually round to two decimal places, turning 8.3333 into 8.33, so check which precision your employer applies.
Add the hours and minutes first and convert once at the end. 37 h 50 min is 2,270 minutes, about 37.83 decimal hours, and 37.83333333 at an hourly rate of 20 gives about 756.67. Converting each day to two decimals and adding afterwards can land a cent or two away from that figure.
