In this application, wire spacing's in the "Calculate Wire Size" tab are calculated based on the nominal wire sizes and are rounded up to the nearest half wire size number. Wire sizes in the "Calculate Wire Spacing" tab are based on wire sizes input and the wire spacing's are calculated and rounded up to the nearest one-half inch. Wire can be produced where the area drawn is drawn to the third decimal place. For example a #5 rebar actual area is 0.3079615 and so on. Wire can be drawn to an area equal to 0.307 square inches.
