Decimal Hours Converter
Convert HH:MM time to decimal hours and back, ideal for timesheets and payroll.
Convert hours and minutes (like 2:30) into decimal hours (2.5) for payroll and timesheet calculations, or go the other way from a decimal value back to HH:MM. Both fields update live and stay in sync.
How to use
- Enter a time as HH:MM, e.g. 2:30.
- Or enter a decimal number of hours, e.g. 2.5.
- The other field updates automatically; copy either value.
