Minutes to decimal hours chart (for timesheets)
Timesheets and payroll systems often ask for minutes as a decimal. Divide the minutes by 60 and round to two places:
| Minutes | Decimal hours |
|---|---|
| 1 | 0.02 |
| 5 | 0.08 |
| 10 | 0.17 |
| 15 | 0.25 |
| 20 | 0.33 |
| 25 | 0.42 |
| 30 | 0.50 |
| 35 | 0.58 |
| 40 | 0.67 |
| 45 | 0.75 |
| 50 | 0.83 |
| 55 | 0.92 |
Worked examples
- 7 hours 40 minutes: 40 ÷ 60 = 0.67, so the total is 7.67 hours.
- 7.8 hours: 0.8 × 60 = 48, so it is 7 hours 48 minutes.
- 8.25 hours: 0.25 × 60 = 15, so it is 8 hours 15 minutes.
Rounded decimals add up to small differences. Seven hours 40 minutes is really 7.6667 hours, and two decimal places make it 7.67. Many U.S. employers round clock time to the nearest quarter hour, and federal wage rules allow it when the rounding is neutral over time. Your employer's policy or your state's rules decide how your own time is rounded, so ask payroll if the numbers matter.
Payroll systems often show hours as decimals, so 8.5 hours means 8 hours and 30 minutes, not 8 hours and 50 minutes. To add or subtract times, use our hours and minutes calculator.
Frequently asked questions
How do I convert decimal hours to minutes?
Multiply the decimal part by 60. For 7.8 hours, 0.8 × 60 = 48, so 7.8 hours is 7 hours and 48 minutes.
How do I convert hours and minutes to decimal?
Divide the minutes by 60 and add it to the hours. For 6 hours and 20 minutes, 20 ÷ 60 = 0.33, so it is about 6.33 hours.
What is 15 minutes as a decimal?
15 minutes is 0.25 hours, because 15 ÷ 60 = 0.25. Likewise 30 minutes is 0.5 hours and 45 minutes is 0.75 hours.
Why is 7.5 hours not 7 hours and 50 minutes?
The part after the decimal point is a fraction of one hour, not a count of minutes. 0.5 of an hour is 30 minutes, so 7.5 hours is 7 hours and 30 minutes.
