A square of side x is equivalent to a circle of x * 1.273 The reciprocal is 0.785 >I have a couple of strings to replace on a Schimmel (monochords) and I'm >wondering how to calculate like replacement strings using round core wire. Hexagonal wire, I presume. Measure across the flats, square the result, multiply that by 1.103 and take the square root of the product. =SQRT(1.103*(hexaf^2)) so if the hexagonal wire measures 0.9 mm across flats you will need a round wire of diameter 0.945 mm. or mwg 16-1/2 to get the equivalent volume or mass.
