The formula to convert hours into days is simple: divide the number of hours by 24. One day has exactly 24 hours, so to find how many days correspond to a given hours value, you split the total hours into 24-hour segments.

Mathematically, it looks like this:

Days = Hours ÷ 24

For example, with 405 hours:
