List, Can you help us convert the "N/mm2" description of tensile strength to "lb./in2" ? We are re-restringing a Viennese grand (Anton Pokorney) c.1850, which appears to have been "foreshortened" around the turn of the century. (Several clues lead us to this conclusion including evidence that the case has been altered, that the plate has been cut, a notation in an inaccessible location dated 1903 and round, rather than oval, tuning pins.) The piano is straight strung, the bass strings are brass wound uni-chords and steel wound bi-chords. We are exploring several types of wire and find some analayzed with the formula N/mm2 and others with lb./in2, so it is hard to compare them. We thank you for any light you can shed on this for us!
