18 Minutes in Decimal Hours Is 0.30

18 minutes in decimal hours is 0.30. 18 ÷ 60 = 0.30 exactly. Decimal hours = minutes / 60. Write the payroll decimal, not the clock digits pasted after a dot. 7:30 = 7.50 hours, not 7.30; 8.15 hours = 8 h 9 min.

How this conversion works

18 ÷ 60 = 0.30. That lands exactly on two decimal places, so the timesheet figure is not a rounded guess.

This sits on a tenth of an hour. Six minutes is 0.10, so time clocks that round to the tenth land on a number like this one.
