24 hours is 1 day.
Math: 24 ÷ 24 = 1
36 hours is 1.5 days.
Math: 36 ÷ 24 = 1.5
48 hours is 2 days.
Math: 48 ÷ 24 = 2
72 hours is 3 days.

1 hour is 1/24 of a day.
As a decimal, that’s 0.0416667 days (repeating).
Some schedules use a workday (often 8 hours) instead of a full 24-hour day.
For time conversions, clarify if you mean:
Time zones don’t change basic conversion math. Hours to days still uses 24 hours per day.
Time zones matter when you compare clock times in different places.
Daylight saving time can make a local day 23 or 25 hours in some regions.
For most conversions, people still use 24 hours = 1 day. For exact clock-based events, check the date and location.
Rounding depends on what you need:
Example: 100 hours ÷ 24 = 4.1667 days
Rounded to 2 decimals: 4.17 days
