Decimal Hours Calculator
Convert hours and minutes to decimal hours for payroll and timesheets, or turn a decimal back into hours and minutes.
Notes
- Common conversions: 15 minutes is 0.25, 20 minutes is 0.33, 40 minutes is 0.67, 50 minutes is 0.83.
- Two decimal places lose at most 18 seconds per entry, which is why payroll uses them as standard.
Common questions
- Why is 20 minutes 0.33 and not 0.2?
- Because an hour has 60 minutes, not 100. 20 divided by 60 is 0.3333, which rounds to 0.33 at two decimal places.
