Military time to standard time

Hi everyone, I'm having a problem with a time sheet I'm working on. Let's just use cell A1 for example. I want to type 17:45 in the cell, and then I want the cell to display 5:45 PM when I click off of it. Any and all help would be greatly appreciated, thanks in advance.

Format the cell with the format you want it displayed as.
I just tested it by entering 17:45 and it displayed 5:45 PM as you wanted.
