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

  1. Enter a time as HH:MM, e.g. 2:30.
  2. Or enter a decimal number of hours, e.g. 2.5.
  3. The other field updates automatically; copy either value.

Frequently asked questions

Why convert time to decimal hours?
Payroll and billing systems usually need decimal hours (2.5) rather than clock time (2:30) to calculate wages or invoices.
How is rounding handled?
Decimal-to-HH:MM conversion rounds to the nearest minute, and HH:MM-to-decimal rounds to two decimal places.
Can I enter more than 24 hours?
Yes, the tool supports durations beyond a single day, e.g. 30:15 or 30.25 decimal hours.
