Enter a decimal hours value (e.g. 1.5) to convert it into hours and minutes — ideal for timesheets.
Payroll systems use decimal hours because they multiply cleanly by an hourly rate. The whole-number part is the hours; multiply the fractional part by 60 to get the minutes.
So 7h 45m equals 7.75 hours and 0h 15m equals 0.25 hours. The table below lists the most common values.
| Decimal hours | Hours & minutes |
|---|---|
| 0.1 | 0h 6m |
| 0.25 | 0h 15m |
| 0.33 | 0h 20m |
| 0.5 | 0h 30m |
| 0.66 | 0h 40m |
| 0.75 | 0h 45m |
| 0.9 | 0h 54m |
| 1 | 1h 0m |
| 1.25 | 1h 15m |
| 1.5 | 1h 30m |
| 1.75 | 1h 45m |
| 2 | 2h 0m |
| 7.5 | 7h 30m |
| 7.75 | 7h 45m |
| 8 | 8h 0m |

A time format only decides how a moment is written — not when it happens. Military time, standard time, Unix timestamps, and decimal time are different notations for the same information.
Converting between them is therefore exact and never changes. The only rounding is in decimal time, where seconds are rounded to whole minutes.
Military time is used by the military, aviation, hospitals, and emergency services because it is unambiguous. Unix timestamps live in databases, log files, and APIs. Decimal time appears on timesheets and in payroll.
Enter a decimal hours value (e.g. 1.5) to convert it into hours and minutes — ideal for timesheets.
The whole-number part is the hours; multiply the fractional part by 60 to get the minutes. So 1.5 hours is 1 hour 30 minutes, and 0.25 hours is 15 minutes.
Timesheets and payroll use decimal hours because decimals multiply cleanly by an hourly rate. 7 hours 45 minutes becomes 7.75 hours.
Yes. Converting between time formats is a pure notation change — the same moment, just written differently. There is no rounding except minute-rounding for decimal time.
