Why decimal hours matter for payroll

Most timesheet and payroll systems expect hours worked as a decimal number (like 7.75) rather than hours and minutes (7h 45m), since decimal hours multiply cleanly against an hourly rate. This tool converts in both directions, so you can move between the clock-time format people read naturally and the decimal format payroll software expects.

Common uses

  • Converting worked hours and minutes into decimal hours for payroll entry
  • Turning a decimal hours figure back into a readable hours-and-minutes format
  • Double-checking timesheet totals before submission
