TIME TO DECIMAL
How do I convert time to decimal hours?
Calculation notes
Decimal hours = hours + minutes ÷ 60. Decimal hours × 60 rounds to the nearest minute.
- 15 min = 0.25 h
- 30 min = 0.50 h
- 45 min = 0.75 h
How it works
- For hours and minutes, enter each number separately; minutes must be from 0 to 59.
- Convert to decimal hours, where minutes are divided by 60.
- Or enter decimal hours to get an HH:MM duration rounded to the nearest minute.
Example
7 hours 45 minutes equals 7.75 decimal hours. In the other direction, 2.67 decimal hours rounds to 02:40 in HH:MM.
