# Convert times

Let's say you want to find out how many hours there are in five and a half days, or how many days there are in 3.45 years, or how many months have passed between a beginning date and an ending date. There are several ways to convert times.

 A Hours 10.5833 12.25 Formula Description (Result) =TEXT(A2/24, "h:mm") Hours since 12:00 AM (10:35) =TEXT(A3/24, "h:mm") Hours since 12:00 AM (12:15)

Note: You can also apply the time format without using the TEXT function to specify the format. To view the number as a time, select the cell, and on the Home tab, in the Number group, click the arrow next to the Number Format box, click More Number Formats, click Custom in the Category list, and then click a custom format in the Type box. However, if you use both a format applied with the TEXT function and number format, the TEXT function takes precedence.
