Making sense of decimal timesheet totals

Payroll and timesheet systems commonly log hours in decimal form (like 7.75 hours) since it is easy to add and multiply for pay calculations, but that same decimal figure is hard to picture in familiar clock time until converted.

Worked example

For 7.75 decimal hours:

Total Seconds = 7.75 x 3600 = 27,900 seconds

Result = 7h 45m 0s
