Interested in fluorocarbon strings for clawhammer. covered this topic.

Here is a nylon to fluorocarbon conversion chart from a harp maker.

Have a folk harp with fluorocarbon strings and nylon and am replacing it with a new one that has fluorocarbon strings and no nylon.
Considering fluorocarbon strings on my clawhammer banjo which has steel strings.

Anyone having good luck finding the correct size fluorocarbon strings?

I used Savarez fluorocarbons for this comparison: .  (There are sound samples there.  I'm shocked by how much my ears and fingers have gone downhill since then, but my wife can tell which is which just listening with laptop speakers.)  My source was  Rather than charts, the key to remember is that the densities of nylon to fluorocarbon to steel go approximately like 1 : 2 : 8 .  Very simple, idealized physics suggests that the string weights (or density per unit length) for the same scale length, pitch, and tension should be the same.  So, the diameters should go like  1 :  0.71  :  0.35  for  nylon  :  fluorocarbon  :  steel.  (This ignores the effect of stretching [which is addressed in my linked write-up] and agrees roughly with the Fisher Harps chart.)  D'Addario used this same formula in their on-line, interactive, tension estimating tool.  (The guy who heads their string R&D took the relevant physics course from me in college.  However, that tool is still under revision and is promised to reappear sometime this year.)

Here is the equivalent based on the nylgut string set (except for the 4th D string X)

Nylgut : 56 - 65 - 78 - X - 56

Fluocarbon : 48 - 57 - 66 - X - 48

personally I take a little bigger for the G string : ( nylgut 82 / fluocabon 72)

You can also use "gamut string calculator" to determine the correct diameter according to scale lenght , Frequency and Tension in Kg
