Dear Ted,

If you know the density of the string material, you get a factor for diam conv. thus:

from the string equation it follows, that the diameters d1, d2 of two string substances 1, 2 with density1 and density2  behave as

  d2/d1 = Sqrt (density1/density2) = factor x/nyl  .

substance  x             nylon 6.12    gut, nylgut, sugar nylgut NGE  carbon/All. KF

density (kg/m^3)     1070              ca 1300   1220                  ca.1780

factor x/nylon            1 0,91                         0,94                     0,78


Best wishes

    Dear wise luters:
    When converting strings from nylon to gut to a synthetic gut, are there
    simple multiplication factors that one can use to determine the
    diameter of a replacement string? For example, if I have a 1mm nylon
    string, and I want to replace it with a gut or synthetic gut, can one
    simply multiply the diameter by a factor -  based on the densities of
    the material - to find the diameter of the replacement string (pitch,
    string length, and room temperature being same)?
    Sorry for the complicated question; I assume the answer will more
    simple.
    Also, are 'Nylgut' and 'Alliance' strings material the same density?
    And lastly, Any recommendations for user friendly online string
    calculators?
    Apologies that the questions may have been previously addressed in this
    group-
    Thanks,
    ted jordan
