What is Hours and Minutes to Decimal Converter?
An Hours and Minutes to Decimal Converter is a tool that turns clock time (hours and minutes) into the decimal hours that payroll systems use.
Payroll software multiplies hours by a rate, so time must be in base 10. Clock minutes run in base 60. 8:30 means 8.5 hours, not 8.30 hours.
