The Conversion Formula
Decimal hours = hours + minutes ÷ 60. For 7 hours 30 minutes that is 7 + 30 ÷ 60 = 7.5. The seconds field, when used, adds seconds ÷ 3600.
- 7h 30m = 7.50 decimal hours
- 7h 15m = 7.25 decimal hours
- 7h 45m = 7.75 decimal hours
- 7h 25m = 7.4167 decimal hours
Why Decimal Hours Matter
Payroll systems and timesheet templates usually expect a single decimal number per day. Entering 7:30 where 7.50 is expected understates the time by 20 minutes — this converter exists to prevent that mistake.
