text: You can get by with:\n"=A1 * 100"  (without quotes)\nThen set the cell format to Percentage.\n\nMany times, Excel will convert the number to percent if you choose that number formatting.  You can do this by clicking on Format | Cells and then select the Number tab.  Choose Percentage.  \n\nIt depends on how your spreadsheet is laid out, and without an example to look at, I can't give you a specific answer.  However, you can play around with:\n"=A1 * 100" \n"=A1 * 0.01"  \n\nDepending on your original number, that will probably give you the answer you need.  Play around with those.
