The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units. The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, ...

Using the SI units of viscosity, shear stress was in N/m2and shear rate was in (m/s)/m = 1/s, so dynamic viscosity has units of Ns/m2(newton-seconds per meter squared) or Pa s (pascal-seconds). However, the most common unit of viscosity is the dyne-second per square centimeter ...
Earlier, kinematic viscosity was measured using the Saybolt viscometer, expressing the units in Saybolt universal seconds (SUS). Other abbreviations such as SUV (Saybolt universal viscosity) or SSU (Saybolt seconds universal) are sometimes used. Related Articles: Unit Of Resistance Unit Of Conductivity...
In SI units ν– Kinematic viscosity, m2/s μ– Dynamic viscosity, kg/m · s ρ– Density, kg/m3 In USCS units, the dynamic viscosity μ is measured in lb · s/ft2. In SI units, μ is stated as kg/m · s, Pascal · s (or Poise), or centipoise (cP). ...
The viscosity is typically reported in centistokes (cSt), equivalent to mm2/s in SI units, and is calculated from the time it takes oil to flow from the starting point to the stopping point using a calibration constant supplied for each tube. In most commercial oil analysis labs, the ...
