How the conversion works

There are 24 hours in a day, so to convert days to hours you multiply by 24. So 1 day is 24 hours, 3 days is 72, and half a day is 12. The number grows because an hour is the smaller unit, and the relationship is exact. It is the reverse of turning hours into days, where you would divide by 24 instead.

Why convert days into hours

Hours give a finer view of a span that is quoted in days. If you are scheduling work across a few days and want to know how many hours that really is, sizing up availability, or lining a day-based estimate up against hourly figures, hours are the unit that lets you do it. A three day window is easier to plan against once you see it as 72 hours, and a day and a half reads clearly as 36.

An example

Take 3 days. Multiply by 24 and you have 72 hours. A day and a half is 36 hours, and a week, 7 days, is 168 hours. The leftover part of a day shows as the decimal, so 2.5 days is 60 hours.
