Why go through the trouble of converting them yourself? Just have Excel do it for you. Here's one way to do it: =IF(AB4>=89.5,"A",IF(AB4>=79.5,"B",IF(AB4>=69.5,"C",IF(AB4>=59.5,"D","F" )))) Here, my percentage grade was in column AB (row 4) and the formula was in column AC. In column AC, it will tell me what letter grade is associated with the percentage. (I know, it's not exactly difficult to do this yourself, but it's still faster to put this formula in once and copy it for all students than to manually put the grade in; less chance of an error, too.) I think that there may be a problem with this if you're using the +/- system, as I seem to remember Excel having a maximum number of if/then arguments it will allow. By the way, a neat spreadsheet trick is to use a row that includes the maximum point value for each assignment, basically a "dummy student" (insert your own snide comment here, I'll refrain) with a perfect score. That "student's" score is then summed in the same column as everyone else's. Then, you set up your "percentage column" so that it divides each student's total number of points by the (automatically calculated) maximum number of points. That means you don't have to keep changing your formulas every time you grade a new assignment; you only need to add the point value for the assignment. Of course this only works if you set up your spreadsheet at the beginning of the semester with all of your possible assignments having their own columns. You can insert additional assignments later, but then you'll have to change the formulas (because the formula used to calculate the sum of each student's scores won't take the inserted column into account)..
