Timecard GuruHow this conversion works
Keep the 9 whole hours. Convert the minutes on their own: 30 ÷ 60 = 0.50. Add that fraction to the hours: 9 + 0.50 = 9.50.
Write 9.50 on the timesheet. Do not write 9.30. Putting the minutes after the dot is the usual mix-up, and it short-changes the time. 30 minutes is 0.50 of an hour, so 9 hours 30 minutes is 9.50, not 9.30.
