The SI unit of kinematic viscosity is square meter per second (m 2 /s), whereas the CGS unit for kinematic viscosity is the stokes (St), named after Sir George Gabriel Stokes. In U.S. usage, stoke is sometimes used as the singular form. The submultiple centistokes (cSt) is often used instead.
In this page we briefly discuss the most common units for the two main types of viscosity: dynamic and kinematic. Units for Dynamic Viscosity. The most commonly used unit for dynamic viscosity is the CGS unit centipoise (cP), which is equivalent to 0.01 Poise (P). This unit is used in honor of French physicist, Jean Léonard Marie Poiseuille ...
Viscosity generally means dynamic viscosity. It is the resistance to the flow of a fluid. Stress is given by, Units of dynamic viscosity are: 1. kg/(m.s) 2. N.s/m ^ 2 3. Pa.s 4. P (Poise) = 0.1 Pa.s 5. cP (Centipoise) = 0.001 Pa.s Note: Viscosity ...
1869), this is the cgs unit of viscosity, equivalent to dyne-second per square centimetre. It is the viscosity of a fluid in which a tangential force of 1 dyne per square centimetre maintains a difference in velocity of 1 centimetre per second between two parallel planes 1 centimetre apart.
Saybolt Universal Seconds (or SUS) is an alternative unit for measuring viscosity. The efflux time is Saybolt Universal Seconds (SUS) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer - under a carefully controlled temperature and as prescribed by test method ASTM D 88 ...
The SI unit of viscosity is the pascal-second (Pa·s). > The viscosity of a fluid is a measure of its resistance to flow. We usually think of the viscosity of a liquid as its "thickness". For example, we say that honey is "thicker" (has a higher viscosity) than water. One way to measure viscosity is to place the fluid between two flat parallel plates and slide one plate past ...
Up till now, all my physics calculations are worked out using SI units. That means I'm entering meters, Kg and seconds. I do this for working out dynamic viscosity η. But, now I've come across a formula to work out centistokes (a unit of kinematic viscosity) from dynamic viscosity and mass, which is a unit worked out using cgs units.

It is the viscosity of a fluid in which a tangential force of 1 dyne per square centimetre maintains a difference in velocity of 1 centimetre per second between two parallel planes 1 centimetre apart. Even in relation to high-viscosity fluids, this unit is most usually encountered as the centipoise (cP), which is 0.01 poise.
There are two related measures of fluid viscosity which are known as dynamic and kinematic viscosity. Dynamic viscosity is also termed "absolute viscosity" and is the tangential force per unit area required to move one horizontal plane with respect to the other at unit velocity when maintained a unit distance apart by the fluid.
