How do I format a number to the 1/16ths, but display the answer as an

You cannot do that just with formatting.

If you merely set the format to display as fraction with up to two digits,
which has been suggested, then you will not round to 16ths.

You *DO* need to set the format to fraction with up to two digits. But:

What is required is either a VBA routine, which will alter your entry "on the
fly" to round to 16ths, or set up your worksheet so that the value is entered
in one cell; and then in a "helper column" you have a formula to do the
rounding: e.g. =ROUND(A1*16,0)/16
