Create a helper column.
Insert a column.
Use the formula =a1*2.54
Copy it down.

Now you have both in and cm.
You can either keep them, copypaste specialvalues the helper column, and
delete the original.

I need to convert numbers in 500 separate cells in one sheet from
centimeters
to inches. I can do one-by-one using the convert function and inputing the
cell location in the number field, "cm" in the "from_unit" field, and "in"
in
the "to_unit" field. However I need to do north of 500 of these. How do
you
do that using Microsoft Office Excel 2007?
