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.
DekapoisedP
Target UnitThe dekapoise (dP) is a unit of dynamic viscosity, which quantifies a fluid's resistance to flow under applied stress. It is defined as 10 poise, where one poise is equivalent to 0.1 Pascal-seconds (Pa·s). This unit is often used in various industries to characterize the flow behavior of liquids, particularly in the food, cosmetics, and chemical sectors. The use of the dekapoise allows for easier expression of viscosity values that are significantly higher than typical measurements in poise, thus facilitating comparisons and assessments of fluid properties.
Current Use
Dekapoise is commonly used in industries where understanding fluid flow is essential, such as food processing, pharmaceuticals, and cosmetics. Laboratories often employ this unit when conducting rheological measurements, which assess how substances deform and flow under stress. The dekapoise facilitates communication of viscosity characteristics among engineers, scientists, and manufacturers, ensuring that specifications align with practical applications.
Fun Fact
The poise is named after Jean Léonard Marie Poiseuille, who is also known for his work in fluid dynamics.

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.

Dekapoise
viscosity • Non-SI
Definition
The dekapoise (dP) is a unit of dynamic viscosity, which quantifies a fluid's resistance to flow under applied stress. It is defined as 10 poise, where one poise is equivalent to 0.1 Pascal-seconds (Pa·s). This unit is often used in various industries to characterize the flow behavior of liquids, particularly in the food, cosmetics, and chemical sectors. The use of the dekapoise allows for easier expression of viscosity values that are significantly higher than typical measurements in poise, thus facilitating comparisons and assessments of fluid properties.
History & Origin
The concept of viscosity has been studied since the time of Newton, who introduced the idea of a coefficient of viscosity in the early 18th century. The poise was named in honor of the French physicist Jean Léonard Marie Poiseuille, who studied the flow of fluids through pipes. The dekapoise was established as a convenient metric unit for measuring high viscosities, allowing scientists and engineers to express values that would otherwise be cumbersome in poise.
Etymology: The term 'dekapoise' combines the prefix 'deka-', meaning ten, with 'poise', named after Jean Léonard Marie Poiseuille.
Current Use
Dekapoise is commonly used in industries where understanding fluid flow is essential, such as food processing, pharmaceuticals, and cosmetics. Laboratories often employ this unit when conducting rheological measurements, which assess how substances deform and flow under stress. The dekapoise facilitates communication of viscosity characteristics among engineers, scientists, and manufacturers, ensuring that specifications align with practical applications.
💡 Fun Facts
- •The poise is named after Jean Léonard Marie Poiseuille, who is also known for his work in fluid dynamics.
- •Viscosity measurements can vary significantly with temperature; for example, heating honey will decrease its viscosity.
- •The term 'dekapoise' is relatively rare compared to poise, as most applications tend to use either poise or centipoise.
