To convert a measurement in hours to a measurement in days, divide the time by the following conversion ratio: 24 hours/day.

Since one day is equal to 24 hours, you can use this simple formula to convert:

days = hours ÷ 24

The time in days is equal to the time in hours divided by 24.

For example, here's how to convert 48 hours to days using the formula above.
days = (48 hr ÷ 24) = 2 d
