    Abstract

    This table gives values for converting kinematic viscosity in centistokes to Saybolt Universal viscosity in seconds at 100 F and at 210 F. Conversion values are given for a range of kinematic viscosity from 1.77 to 500 cs. The relationship between Saybolt and kinematic viscosities is linear above 20.0 cs. The viscosity conversion values in this table have been calculated in accordance with the Standard Method for Conversion of Kinematic Viscosity to Saybolt Universal Viscosity (ASTM Designation: D 446). These kinematic viscosity values are based upon the standard value for distilled water of 1.0038 cs at 68 F and are given in increments smaller than are officially measured by, or reported for the Saybolt Universal Viscometer. The Saybolt Viscosity values obtained from this Table, following the reporting procedure outlined in the Standard Method of Test for Saybolt Viscosity (ASTM Designation: D 88, should be reported to the nearest 0.1 sec for viscosity values below 200 sec and to the nearest whole second for values 200 sec or above. Viscosity values not listed but which are within the range given in Table I may be obtained by linear interpolation.
