To convert these fractional values to decimal hours, just multiply by 24. For example .5 * 24 = 12 hours, .24 * 24 = 6 hours, etc.
Durations over 24 hours
To calculate and display time durations over 24 hours, you’ll want to use a custom time format like [h]:mm. Otherwise, the duration will “reset” every 24 hours, in the same way that a clock “resets” each day. More on custom number formats here. Author
