Unit Explanations
PoiseP
Source UnitThe poise (symbol: P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when a velocity gradient of one reciprocal second is applied. In essence, one poise corresponds to a viscosity of 1 g/(cm·s). This unit is particularly useful in fields involving fluid mechanics and rheology, where the flow properties of liquids are analyzed.
Current Use
The poise is commonly used in laboratories and industries that deal with fluid properties, such as food processing, pharmaceuticals, and materials science. It is particularly relevant for measuring the viscosity of non-Newtonian fluids and biological fluids, such as blood, where understanding flow behavior is crucial. While the SI unit pascal-second is preferred in many scientific contexts, the poise remains popular in specific applications.
Fun Fact
The poise was historically significant in the study of blood flow, influencing medical research and treatments.
ExastokesESt
Target UnitThe exastokes (symbol: ESt) is a non-SI unit of dynamic viscosity, defined as 10^18 stokes. It measures the internal friction of fluids, indicating their resistance to flow. The stoke, the base unit for kinematic viscosity in the centimeter-gram-second (CGS) system, relates to the area a fluid will cover under the influence of gravity. Therefore, an exastokes represents an extremely high value of viscosity, typically encountered in theoretical discussions or specific high-viscosity materials.
Current Use
Today, the exastokes is primarily used in advanced scientific research and theoretical studies involving ultra-viscous materials, such as certain polymers, biofluids, and complex fluids. Its use is largely confined to academic and industrial settings where extremely high viscosity values need to be quantified, helping scientists and engineers understand fluid behavior under various conditions.
Fun Fact
The viscosity of honey can be approximately 10,000 times that of water, making it a practical example of a high-viscosity fluid.

viscosity • Non-SI
Definition
The poise (symbol: P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when a velocity gradient of one reciprocal second is applied. In essence, one poise corresponds to a viscosity of 1 g/(cm·s). This unit is particularly useful in fields involving fluid mechanics and rheology, where the flow properties of liquids are analyzed.
History & Origin
The poise was named after the French scientist Jean Louis Marie Poiseuille, who made significant contributions to the study of fluid dynamics in the 19th century. His work focused on the flow of liquids in tubes, and he is best known for deriving Poiseuille's law, which describes the laminar flow of incompressible fluids. The term was introduced in the 19th century and has been widely used in scientific literature since then, particularly in relation to the study of blood viscosity and other biological fluids.
Etymology: The term 'poise' is derived from the surname of Jean Louis Marie Poiseuille, reflecting his foundational work in fluid dynamics.
Current Use
The poise is commonly used in laboratories and industries that deal with fluid properties, such as food processing, pharmaceuticals, and materials science. It is particularly relevant for measuring the viscosity of non-Newtonian fluids and biological fluids, such as blood, where understanding flow behavior is crucial. While the SI unit pascal-second is preferred in many scientific contexts, the poise remains popular in specific applications.
💡 Fun Facts
- •The poise was historically significant in the study of blood flow, influencing medical research and treatments.
- •One poise is equivalent to 0.1 pascal-seconds, showing the relationship between CGS and SI units.
- •The term 'centipoise' (cP) is commonly used in industries, where 1 P equals 100 cP, making it easier to express lower viscosities.

Therefore, an exastokes represents an extremely high value of viscosity, typically encountered in theoretical discussions or specific high-viscosity materials.
History & Origin
The concept of viscosity dates back to the early study of fluid dynamics, but the term 'stokes' was introduced by the British scientist Sir George Gabriel Stokes in the 19th century. The exastokes emerged as a convenient unit for expressing extraordinarily high values of viscosity in scientific literature and research, especially in theoretical physics and engineering contexts.
Etymology: The name 'exastokes' derives from the prefix 'exa-', meaning 10^18, combined with 'stokes', named after Sir George Gabriel Stokes.
Current Use
Today, the exastokes is primarily used in advanced scientific research and theoretical studies involving ultra-viscous materials, such as certain polymers, biofluids, and complex fluids. Its use is largely confined to academic and industrial settings where extremely high viscosity values need to be quantified, helping scientists and engineers understand fluid behavior under various conditions.
💡 Fun Facts
- •The viscosity of honey can be approximately 10,000 times that of water, making it a practical example of a high-viscosity fluid.
- •In extreme conditions, such as in the interior of planets, the viscosity can reach values in the range of exastokes.
- •Certain synthetic materials can be engineered to have viscosity values that fall into the exastokes range, pushing the boundaries of traditional fluid dynamics.
