9. To convert these to actual numbers, use the following formula:
   Code:

   =LEFT(A1,LEN(A1)-1)*RIGHT(A1,1)

   (Note: Replace "A1" with the cell reference of the first cell in your column.)
10. Copy the formula down to the rest of the cells in the column.
11. Finally, select the entire column and click on the Number Format dropdown in the ribbon. Select Number to format the cells as numbers.
