Question 1

How do I convert hours and minutes to decimal hours?

Accepted Answer

To convert minutes to decimal hours, divide the minutes by 60. For example, 15 minutes is 15/60 = 0.25 hours, 30 minutes is 30/60 = 0.50 hours, and 45 minutes is 45/60 = 0.75 hours. Add this back to the total hours to get decimal hours (e.g. 8 hours and 15 minutes is 8.25 decimal hours).

Question 2

How does automatic overnight shift detection work?

Accepted Answer

If the end time entered is chronologically before the start time (e.g., start 10:00 PM and end 6:00 AM), the calculator automatically assumes an overnight shift and adds 24 hours to the end time. This prevents negative totals and calculates the elapsed duration correctly.

Question 3

Why do employers require decimal hours for payroll?

Accepted Answer

Decimal hours simplify payroll arithmetic. Multiplying an hourly wage by hours and minutes (like 7 hours and 45 minutes) yields an incorrect total. Converting 45 minutes to 0.75 decimal hours yields 7.75 hours, which can be directly multiplied by the pay rate (e.g., $20.00/hour * 7.75 = $155.00).
