Thank you Arto. Did you see the reply I had from Saverez? It appears that over 0.95mm the strings have a flouro carbon(?) or whatever core which is overlaid with a thinner sheath/coating/winding(?) of the same material. I presume this is done to increase flexibility (and elasticity?) of these thicker strings.
Saverez used to make nylon strings overwound with nylon called NP (not v good); I suppose these thicker sheathed/coated KF strings superseded the old NP. Have you used them? But isn't it odd that they, an established string maker, are unable to provide a conversion table or factor? So thank you for your work.

I went to a pharmacy and asked them to measure the weight of a piece of such strings. Then I calculated the density of the material, knowing the diameter, length and weight - using the "sub-calculator" of my 1st version string calculator: [1]http://www.cs.helsinki.fi/u/wikla/mus/Calcs/wwwscalc.html#P1 I got the density 1791 Kg/m3, which is clearly more that gut (about 1300 Kg/m3). In my calculators I call these strings "carbon". I do not know, if Savarez has changed their material since, but to me this density parameter has worked well...
