Bridging the digital-to-tape gap

CAD drawings, spreadsheets and product specs speak decimal inches (3.4375); your tape measure speaks fractions (3 7/16). The calculator finds the <strong>nearest fraction down to 1/32 of an inch</strong> and shows how far off it is — most of the time the nearest 1/16 is the practical answer and the 32nd is the machinist's.
