Viscosity Converting Chart - The Engineering ToolBox
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 …

Mar 23, 2011 · For example, a lubricant with an ISO grade of 32 has a viscosity within the range of 28.8-35.2, the midpoint of which is 32. Rule of Thumb: The comparable ISO grade of a given product whose viscosity in SUS at 100°F is known can be determined by using the following conversion formula: SUS @ 100°F/5=cSt @ 40°C. cst= 0.226xSUS-(195/SUS)
The relationship between saybolt seconds and kinematic viscosities is linear above 75 cSt. To Convert Kinematic Viscosities above 75 cSt to SUS at 210°F, multiply by 4.664.

Aug 12, 2002 · They are both known as kinematic viscosities (a measure of restrictive flow). Essentially one is ISO (Internal standards Organization) cSt is measured at 40 C and 100 C. SUS is the older "English" Measurement and is measured at 100 F …

HYDRAULIC FLUIDS:SUS Viscosity and Viscosity Index
The viscosity in Saybolt Universal Seconds (SUS) equals the elapsed time. Obviously, a thick liquid will flow slowly, and the SUS viscosity will be higher than for a thin liquid, which flows faster. Since oil becomes thicker at low temperatures and thins when warmed, the viscosity must be expressed as a specific SUS at a given temperature.

Saybolt Universal Seconds (SUS), which is the time in seconds for 60 milliliters of oil to flow through a standard orifice at a given temperature. This viscosity system is still in limited use, although it has been generally replaced by the ISO grading system.
Viscosity is also commonly given as centistokes (cstks) and Saybold Universal Seconds (SSU or SUS). These two units describe the kinematic viscosity, which is the ratio of viscosity to mass density. For the centistoke the relationship is: cP = cSt x …
D2161 Standard Practice for Conversion of Kinematic Viscosity to ...
Jan 28, 2021 · It is recommended that kinematic viscosity be reported in millimetres squared per second, instead of Saybolt Universal Seconds (SUS) or Saybolt Furol Seconds (SFS). This method is being retained for the purpose of calculation of kinematic viscosities from SUS and SFS data that appear in past literature.
(Older SUS or SSU tocurrent cSt. or mm2/s) Assumes that viscosities are at the same temperature and the Viscosity Index is 95. 35 SSU ~ 2.5 cSt 550 SSU ~ 119 cSt 40 SSU ~ 4.2 cSt 600 SSU ~ 129 cSt 45 SSU ~ 5.8 cSt 650 SSU ~ 140 cSt 50 SSU ~ 7.4 cSt 700 SSU ~ 151 cSt 55 SSU ~ 8.8 cSt 750 SSU ~ 162 cSt 60 SSU ~ 10.4 cSt 800 SSU ~ 173 cSt
