The kinematic viscosity of a liquid can be looked upon as the liquid's resistance to flow under its own gravity head. ν = η/ρ. Units for Kinematic Viscosity: ft 2 / s. mm 2 / s. m 2 / s. The following table defines the average Kinematic Viscosity for selected liquid fluids. The data shown yellow can be changes to recallate the selected variables.
Find the dynamic (absolute) viscosity values for a wide range of liquids in both SI (mPa·s) and US customary (lbf·s/ft²) units.
Viscosity is resistance to shear or flow in a fluid - and a measure of the adhesive/cohesive or frictional property. Viscosity arising due to internal molecular friction produces the frictional drag effect. There are two related measures of fluid viscosity - known as dynamic (or absolute) and kinematic viscosity.
Table of data giving the viscosity of many common liquid substances used in process industries.
Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F. Dynamic (Absolute) Viscosity - Converting Chart. Convert dynamic viscosity values between units like Poiseuille - Poise - centiPoise and more. Engine & Gear Oil - Recommended Viscosity vs. Outside Temperature.
Viscosity of Liquids and Gases. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. More commonly used is the dyne sec/cm 2 which is called Poise. One Pa s is 10 Poise. The Poise is used in the table because of its more common usage. Data from Gustafson.
Online calculators, figures and tables with dynamic and kinematic viscosity of liquid and gaseous butane, C 4 H 10, at varying temperarure and pressure, SI and Imperial units. Dynamic (Absolute) Viscosity - Converting Chart
A compiled list of viscosities of various materials. Viscosity is given in centiPoise (cP), equivalent to milliPascal seconds (mPa s). To get the kinematic viscosity (in centiStokes), just divide by the specific gravity of the fluid.

Viscosity, commonly known as thickness, is a measure of how much a liquid resists deformation when a force is applied. There are four types of liquid behavior relating to viscosity.
