Why 7:45 is 7.75, not 7.45
An hour has 60 minutes, not 100, so the minutes on a clock are not hundredths of an hour. Typing 7:45 into payroll as 7.45 shortchanges you by 0.30 of an hour — 18 minutes of pay. Across five shifts a week that is an hour and a half of unpaid time.
| On the clock | Correct decimal | Common mistake | Pay lost at $20/hr |
|---|---|---|---|
| 7:15 | 7.25 | 7.15 | $2.00 |
| 7:30 | 7.50 | 7.30 | $4.00 |
| 7:45 | 7.75 | 7.45 | $6.00 |
| 8:50 | 8.83 | 8.50 | $6.67 |
The quarter hours are worth memorising: 15 minutes is 0.25, 30 is 0.5, 45 is 0.75. For anything else, divide by 60 — or paste the column into the converter above and read the totals.
Minutes to decimal: common questions
How do you convert minutes to decimal hours?
Divide the minutes by 60. That is the whole rule: 15 minutes is 15 ÷ 60 = 0.25, 30 minutes is 0.5 and 45 minutes is 0.75. Add the result to the whole hours, so 7 hours 45 minutes becomes 7.75. Payroll systems store time this way because decimals multiply cleanly by an hourly rate.
Why is 7 hours 45 minutes 7.75 and not 7.45?
Because an hour has 60 minutes, not 100. Writing 7:45 as 7.45 treats the minutes as hundredths and underpays by 18 minutes of pay across a week of such shifts. Converting properly, 45 minutes is three quarters of an hour, which is 0.75 — so the timesheet figure is 7.75 hours.
How do I convert decimal hours back to minutes?
Multiply the decimal part by 60. In 6.35 hours, 0.35 × 60 = 21, so it is 6 hours 21 minutes. The reverse chart on this page lists every tenth and hundredth of an hour with its minutes, which is useful when payroll reports decimals and you want to check them against your own punches.
What is 10 minutes in decimal hours?
10 minutes is 0.17 hours, because 10 ÷ 60 = 0.1666, rounded to two places. Common values worth memorising: 6 minutes is 0.1, 12 minutes is 0.2, 15 minutes is 0.25, 20 minutes is 0.33, 36 minutes is 0.6 and 48 minutes is 0.8. Everything else follows the same division.
How many decimal places should a timesheet use?
Two is standard, and most payroll systems round to two. That leaves small remainders: 20 minutes is 0.3333, stored as 0.33, which is about 24 seconds short. Over a full pay period the difference is cents, but if your employer rounds every entry the same direction, ask for the exact minutes instead.
