To convert hours in decimal format to a valid Excel time, divide by 24. In the example shown the formula in C5 is:
which returns 0.04167, the equivalent of 1 hours. Cell D6 shows the same result formatted as time, which displays 1:00.
How this formula works
In the Excel date system, one day is equal to 1, so you can think of time as fractional values of 1, as shown in the table below:
This means if you have a decimal number for hours, you can simply divide by 24 to get the correct representation of hours in Excel. After dividing by 24, you can apply a time format of your choice, or use the result in a math operation with other dates or times.
In the example, since B10 contains 12 (representing 12 hours) the result is 12/24 = 0.5, since there are 12 hours in a half of day. Once a time format like h:mm has been applied, Excel will display 12:00.
Durations longer than 24 hours
To display hours that represent a duration longer than 24 hours, you'll need to adjust the number format. Just wrap the h in square brackets like so:
To display in minutes, you can do the same thing with m:
To convert minutes in decimal format to a proper Excel time, divide by 1440. In the example shown, the formula in C6 is: = B6 / 1440 Because B6 contains 60 (representing 360 minutes) the result is 60/1440 = 0.04167, since 60 minutes = 1 hour = 1/24...
To convert seconds in decimal format to a proper Excel time, divide by 86400. In the example shown, the formula in C6 is: = B6 / 86400 To display the result as time, apply a time format. Column D shows the same result formatted with [h]:mm. How this...
To calculate the number of hours between two times, you can use a formula that simply subtracts the start time from the end time. This is useful to calculate working time, calculate elapsed time, etc. However, when times cross a day boundary (...
To add a given number of hours to a time, you can add hours divided by 24, or use the TIME function. In the example shown, the formula in D5 is: = B5 + ( C5 / 24 ) Note: make sure results are formatted as time. How this formula works Times in Excel...
To calculate overtime and pay associated with overtime, you can use the formulas explained on this page. In formula in cell I5 is: = ( F5 * H5 ) + ( G5 * H5 * 1.5 ) How this formula works Note: it's important to understand that Excel deals with time...
