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.
ExapoiseE
Target UnitThe exapoise is a non-SI unit of dynamic viscosity, defined as one quintillion poise (10^18 poise). Viscosity is a measure of a fluid's resistance to flow and deformation, with the poise defined as 1 gram per centimeter per second. Given its magnitude, exapoise is typically used in theoretical contexts or specific industrial applications involving extremely viscous materials, where typical viscosity units are impractical. The exapoise is particularly useful in high-viscosity scenarios, allowing scientists and engineers to express values that would otherwise be cumbersome.
Current Use
The exapoise is utilized primarily in specialized fields such as material science, polymer research, and high-viscosity fluid dynamics. It is relevant in scenarios involving extremely dense fluids, such as certain lubricants or industrial coatings. While not commonly used in everyday applications, it serves critical roles in research and development environments focusing on complex fluid behavior.
Fun Fact
The poise was named after Jean Léonard Marie Poiseuille, a pioneer in fluid mechanics.

Poise
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.

Exapoise
viscosity • Non-SI
Definition
The exapoise is a non-SI unit of dynamic viscosity, defined as one quintillion poise (10^18 poise). Viscosity is a measure of a fluid's resistance to flow and deformation, with the poise defined as 1 gram per centimeter per second. Given its magnitude, exapoise is typically used in theoretical contexts or specific industrial applications involving extremely viscous materials, where typical viscosity units are impractical. The exapoise is particularly useful in high-viscosity scenarios, allowing scientists and engineers to express values that would otherwise be cumbersome.
History & Origin
The exapoise emerged in the 20th century, during the development of advanced fluid mechanics and materials science. It was conceived to provide a scale for extraordinarily viscous substances that could not be adequately described using conventional units. The need for such a unit arose particularly in industries dealing with polymeric substances or other highly viscous materials.
Etymology: The term 'exapoise' is derived from the prefix 'exa-', which denotes a factor of 10^18, combined with 'poise', named after French physicist Jean Léonard Marie Poiseuille, who studied fluid dynamics.
Current Use
The exapoise is utilized primarily in specialized fields such as material science, polymer research, and high-viscosity fluid dynamics. It is relevant in scenarios involving extremely dense fluids, such as certain lubricants or industrial coatings. While not commonly used in everyday applications, it serves critical roles in research and development environments focusing on complex fluid behavior.
💡 Fun Facts
- •The poise was named after Jean Léonard Marie Poiseuille, a pioneer in fluid mechanics.
- •Exapoise is rarely encountered in everyday measurements, making it a unique and specialized unit.
- •The viscosity of honey is approximately 2,000 poise, which is equivalent to 2 x 10^-15 exapoise.
