Hours to Days converter
Quick reference
About time units
Time units are the most familiar and the most irregular: 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, then suddenly 7 to a week. The 'year' here is the Julian year of exactly 365.25 days, the astronomer's convention, since the calendar year varies with leap years. These conversions show up in payroll (hours to days), project planning (days to weeks), and anywhere a duration in one unit needs to make intuitive sense in another.
