1) The Saybolt Universal SUS viscosity equivalent (SSU or SUS) to a given kinematic viscosity varies with the temperature at which the determination is made. Check ASTM D 2161 "Standard Practice for Conversion of Kinematic Viscosity to Saybolt Universal Viscosity or to Saybolt Furol Viscosity"
2) Water at 68.4 o F (20.2 o C) has an absolute viscosity of one - 1 - centiPoise .
Note! Viscosity conversions are based on fluids with specific gravity of one .
At temperatures other than 100 or 210°F, convert kinematic viscosity to Saybolt Universal viscosity with
U t = U 100°F (1 + 0.000061 (t - 100)) (1)
where
U t = Saybolt Second Universal (SSU) viscosity at temperature t (°F)
U 100°F = Saybolt Second Universal (SSU) viscosity at 100°F in Saybolt Universal seconds equivalent to kinematic viscosity in centiStokes at temperature t (°F)
