Krebs to Poise Formula

Looking for a decent formula on the net for a Krebs to Poise conversion I’m left empty handed. I found a chart that had listed direct numerical conversions.

Here’s the Best Fit value in the Quadratic form ax^2+bx+c=y

y=0.00419037x^2+(-0.306745)x+6.40025
y=poise
x=krebs

It may be somewhat rough, but since KU is a unitless value…

Got some info from a fellow in Costa Rica that the formula seems to match more closely to Newtonian Poise. Using this for Thixotropic fluids would most likely be innacurate at best! I would agree since Thixotropic fluids require specific velocity differences to accurately determine viscosity at a value differing from standard measuring techniques.
