Centistokes to Saybolt Universal Seconds Conversion



To convert centistokes to Saybolt Universal Seconds, find the centistoke value on the table at left and then read across to find the equivalent value in Saybolt Universal Seconds.



A viscosity of 30 centistokes is equivalent to 140 Saybolt Universal Seconds.


a) If the viscosity is given in centipoise (cp), it can be readily converted to centistokes (cs) by the formula:


centistokes =
specific gravity


b) Centistokes are often designated by cSt.
c) Saybolt Universal Seconds are designated by either SUS or SSU
