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.
HectopoisehP
Target UnitThe hectopoise (hP) is a unit of dynamic viscosity that quantifies a fluid's resistance to flow. It is defined as 100 centipoise (cP), with 1 cP being equivalent to 0.001 Pascal-seconds (Pa·s). The unit is commonly used in various industries to measure the viscosity of liquids, providing a scale that is easy to comprehend for practical applications, especially in contexts where fluids have relatively low viscosities, such as water or light oils. The hectopoise offers a convenient alternative to the more technical Pascal-second in specific applications.
Current Use
Today, the hectopoise is widely used in the food processing, pharmaceutical, and petroleum industries, where accurate viscosity measurements are essential. It serves as a practical unit for engineers and scientists who need to communicate fluid properties effectively. It is particularly advantageous in contexts where low viscosity fluids are prevalent, allowing for easy conversions and comparisons with other common viscosity units.
Fun Fact
The hectopoise is not an SI unit but is commonly used in practical applications due to its convenience.

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.

Hectopoise
viscosity • Non-SI
Definition
The hectopoise (hP) is a unit of dynamic viscosity that quantifies a fluid's resistance to flow. It is defined as 100 centipoise (cP), with 1 cP being equivalent to 0.001 Pascal-seconds (Pa·s). The unit is commonly used in various industries to measure the viscosity of liquids, providing a scale that is easy to comprehend for practical applications, especially in contexts where fluids have relatively low viscosities, such as water or light oils. The hectopoise offers a convenient alternative to the more technical Pascal-second in specific applications.
History & Origin
The hectopoise was introduced as part of the metric system and is derived from the poise, a unit named in honor of the French physicist Jean Léonard Marie Poiseuille, who studied the flow of fluids. The term 'hecto' indicates a factor of 100, making it easier to express values of low viscosity in a more manageable form. It was adopted in scientific literature to bridge the gap between the use of the poise and more common units like centipoise, which are more user-friendly for practical applications.
Etymology: The term 'hectopoise' combines 'hecto,' a metric prefix indicating one hundred, with 'poise,' which originates from the name of the physicist Poiseuille.
Current Use
Today, the hectopoise is widely used in the food processing, pharmaceutical, and petroleum industries, where accurate viscosity measurements are essential. It serves as a practical unit for engineers and scientists who need to communicate fluid properties effectively. It is particularly advantageous in contexts where low viscosity fluids are prevalent, allowing for easy conversions and comparisons with other common viscosity units.
💡 Fun Facts
- •The hectopoise is not an SI unit but is commonly used in practical applications due to its convenience.
- •One poise is equal to 100 centipoise, making the hectopoise a straightforward conversion for low viscosity fluids.
- •In the context of non-Newtonian fluids, the viscosity can change with shear rate, complicating the use of a fixed viscosity unit.
