Simply format the first column as being in fractions with 2 digits allowed.

Insert 1/64 in the first cell of t of the first column, and make the second row cell being equal to row 1 plus 1/64.

Copy this formula from row 2 (in column 1) all the way down column 1 until you reach 2 inches.

The second column is formated as a decimal to 2 significant figures.

The cells in column 2 equals column 1 multiplied by either 2 if working in inches or 50.8 if working in metric.
