| Kinematic viscosity is a measure of the resistive flow of a fluid under the influence of gravity. This measurement is generally displayed in most oil manufacturers respective TDS and/or SDS information data. When two fluids of equal volume are placed in identical capillary viscometers and allowed to flow under the influence of gravity, a viscous fluid takes longer than a less viscous fluid to flow through the tube.

| The most common unit of measure for kinematic viscosity is the square millimeter per second [mm2/s] or the centistokes [cSt]. One square meter per second is equal to one million centistokes. 1 mm2/s = 1 cSt ((http://physics.info/viscosity/))The standard evaluating temperature set for comparison is 40°C (104°F) and 100°C (212°F); example (<wrap hi>Viscosity at 40°C</wrap> ASTM D445 <wrap hi>18.1 mm²/s</wrap>)Therefore, viscosity cSt @ 40°C is 18.1 mm²/s. | The most common unit of measure for kinematic viscosity is the square millimeter per second [mm2/s] or the centistokes [cSt].
