How to Convert Hours to Days
To convert hours to days, divide the number of hours by 24, since there are 24 hours in one day. The result is expressed as a decimal number of days.
Example: 36 hours / 24 = 1.5 days
Or expressed as: 1 day and 12 hours
How to Convert Decimal Days to Days and Hours
When converting decimal days to days and hours, the whole number part gives the full days. The decimal part is then multiplied by 24 to get the remaining hours.

Reading Time in Days and Hours Format
When a total number of hours is converted to days and hours, divide the total hours by 24 to get the full days, then take the remainder as the leftover hours. For example, 100 hours divided by 24 gives 4 full days with a remainder of 4 hours, written as 4 days 4 hours.
Full days: 4
Remaining hours: 100 – (4 x 24) = 4
Result: 4 days 4 hours
