Brian, Here's what I found for music wire: "To find the gauge number of the string, take the micrometer reading, subract .oo5 and divide it by 2. Or: to dind the diameter of the string, multiply the gauge number by 2 and add .005." (A Guide To Restringing by John W. Travis, page 36) This formula seems to work for center pins with the exception I used .010 instead of .005. Keith McGavern Registered Piano Technician Oklahoma Chapter 731 Piano Technicians Guild USA
