I am trying to convert for example 10:00 A.M. from an excel cell that has time format to 10.00. Another example is trying to convert 17:30 Military time to 5.5.

Can this be done? I really appreciate your help and suggestions.

thanks

Not sure what you are trying to do.

If you take the fractional part of the serial number time format and multiply that by 24, you have military time in decimal format.

To expand on IRstuff's post, if your time value is in cell A1, then the following will convert it to a decimal time:

=24*(RIGHT(A1,LEN(A1)-(FIND(".",VALUE(A1))-1)))

I placed 11:30 in cell A1, then I place the formula in cell B1. The result it gave me was 12:00.

What I am trying to get is 11.5.

I appreciate your help. thanks

Change the formatting of cell B1 to "General" or "Number". Looks like Excel sees that formual (when first entered) and automatically changes the formatting of the cell to Time or Custom.

Here's another way, again presuming the time is located in cell A1:

=HOUR(A1)+MINUTE(A1)/60

As KenBolen mentioned in his solution, the format must be set to "Number".

should be simpler than that:

enter 11:30 pm in A1

in B1 put =24*A1

format B1 for "number"

B1 should read 23.5
