How to convert time to decimal hours
An hour has 60 minutes, so every minute is 1/60 of an hour. To write hours and minutes as one decimal number:
- Keep the whole hours as they are. In 7 hours 45 minutes, that is 7.
- Divide the minutes by 60. 45 ÷ 60 = 0.75.
- Add the two together. 7 + 0.75 = 7.75 decimal hours.
Going the other way, multiply the decimal part by 60: 8.6 hours is 8 hours and 0.6 × 60 = 36 minutes.

How many decimal places should I use?
Two decimal places is standard for timesheets and invoices, and this calculator shows that by default along with a more exact figure. Some employers round to the nearest quarter hour (0.25) instead, so check how yours does it.
