Payroll runs on decimal hours, timesheets are written in hours and minutes, and the gap between them causes real money errors. This minutes to decimal hours converter goes both ways: type 7:45 and get 7.75, or type 7.75 and get 7:45. The reference strip underneath covers the values that come up most.
Why 7:45 is not 7.45
Minutes are sixtieths of an hour, so 45 minutes is 45 ÷ 60 = 0.75 of an hour. Typing 7.45 instead of 7.75 loses 18 minutes of pay on a single shift, and repeats every week it goes unnoticed. The arithmetic is set out in converting minutes to decimal hours.
The values worth memorising
Four cover most timesheets: 15 minutes is 0.25, 30 is 0.50, 45 is 0.75 and 6 minutes is exactly 0.10 — which is why legal billing runs in six-minute units, as covered in tracking billable hours. Everything else is minutes divided by sixty.
