From clock times to decimal hours
Start at 08:17, finish at 16:52, and take a 30-minute unpaid break.

Keep the five minutes in the calculation: 8:05 is a duration, while 8.08 is its rounded decimal-hour value. For several shifts, add the unrounded durations first. See the full timesheet example.

For precise calculations, use the full decimal value before rounding. For example, 20 minutes is exactly 1/3 of an hour, displayed here as 0.33.
HOW IT WORKS
Why 45 minutes equals 0.75 hours
A clock hour has 60 minutes. To express minutes as part of an hour, divide by 60. For a full duration, add the whole hours.
For example: 8 hours 45 minutes = 8 + 45 ÷ 60 = 8.75 hours.
To go the other way, keep the whole hours and multiply the decimal part by 60.
For example: 4.25 hours = 4 hours + (0.25 × 60 minutes) = 4 h 15 min.
“Industrial minutes” sometimes means hundredths of an hour. One hundredth of an hour is 36 seconds; it is not one ordinary minute.
PRACTICAL EXAMPLES
Which value belongs on your timesheet?
Subtract breaks first
A shift from 09:00 to 17:30 lasts 8 hours 30 minutes. With a 30-minute unpaid break, the paid duration is 8 hours, or 8.00 decimal hours. Convert the paid duration, not the time between clock-in and clock-out.
Keep minutes until the total
Three tasks of 20 minutes each add up to exactly 60 minutes, or 1.00 hour. Rounding each task to 0.33 first gives 0.99. Add the original durations, then round the final decimal total.
Decimal hundredths are not clock minutes: 0.10 hour is 6 minutes, while 10 minutes is about 0.17 hour. Our timesheet guide works through daily totals, breaks, overnight shifts and rounding policies.
