Timecard GuruHow this conversion works
Keep the 3 whole hours. Convert the minutes on their own: 45 ÷ 60 = 0.75. Add that fraction to the hours: 3 + 0.75 = 3.75.
Write 3.75 on the timesheet. Do not write 3.45. Putting the minutes after the dot is the usual mix-up, and it short-changes the time. 45 minutes is 0.75 of an hour, so 3 hours 45 minutes is 3.75, not 3.45.
