If you want to format a number to display the units, select the
cell(s), go to the "Format" menu, and choose "Cells". In that dialog,
choose the "Number" tab and then "Custom" in the "Category" list. In
the "Type" text box, enter

#,##0.00" Kg-mm"²

You can get the ² character by holding down the ALT key and typing
0178 on the numeric keypad (to the right of the letter keys -- don't
use the numbers above the letters. the leading 0 is required).
