Centipoise = Centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). To find the exact cp for your fluid:

cp= cSt x (weight per gallon x 0.120)

Saybolt Universal second (Often SUS or SSU) is a measure of kinematic viscosity used in classical mechanics. It is the time that 60 cm3 of oil takes to flow through a calibrated tube at a controlled temperature. The SUS is used for oils with flowing time up to 5600[citation needed] seconds, in the range of low to medium viscosity such as machine oils.
