How the hours-to-minutes converter works
Enter a duration in hours or minutes. The other field updates immediately, and the middle button reverses the conversion without changing the length of time.
Use the factor 60
Every hour contains exactly 60 minutes:
Multiply hours by 60 to get minutes. Divide minutes by 60 to return to decimal hours.
Common schedule values
- 0.5 hour is 30 minutes, useful for a short appointment.
- 1.25 hours is 75 minutes, so the extra quarter hour contributes 15 minutes.
- 2.5 hours is 150 minutes. In reverse, 90 minutes is 1.5 hours.
The result describes the same duration in a different unit; no time is added or removed.
Decimal hours are not clock notation
A value such as 1.30 hours means 1 hour plus 0.30 of an hour, which is 78 minutes. It does not mean 1 hour 30 minutes. For that duration, enter 1.5 hours or 90 minutes.
The converter handles durations only. It does not determine start times, time zones, breaks or billable rounding rules.
