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.
MillipoisemP
Target UnitThe millipoise (mP) is a derived unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as one-thousandth of a poise (P), where one poise is the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when flowing with a velocity gradient of one reciprocal second. The millipoise is predominantly used in various scientific and industrial applications to quantify the resistance of fluids to flow under specific conditions. It serves as a practical measurement for low-viscosity liquids.
Current Use
Today, the millipoise is widely used in industries such as food processing, cosmetics, pharmaceuticals, and petrochemicals to determine the viscosity of various liquids. It is essential for quality control and formulation processes, allowing manufacturers to ensure that products maintain the desired texture and flow characteristics. The millipoise is particularly useful for testing low-viscosity fluids, where precise measurements are critical for product consistency and performance.
Fun Fact
The millipoise is often used in laboratories to measure the viscosity of liquids in experiments and formulations.

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.

Millipoise
viscosity • Non-SI
Definition
The millipoise (mP) is a derived unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as one-thousandth of a poise (P), where one poise is the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when flowing with a velocity gradient of one reciprocal second. The millipoise is predominantly used in various scientific and industrial applications to quantify the resistance of fluids to flow under specific conditions. It serves as a practical measurement for low-viscosity liquids.
History & Origin
The millipoise is part of the CGS system of measurement that was widely used in the 19th century. The poise was named after the French physicist Jean Léonard Marie Poiseuille, who studied fluid dynamics and the flow of liquids. The millipoise was subsequently introduced as a convenient subunit to measure lower viscosity values, making it easier for scientists and engineers to work with a wider range of fluids, particularly in laboratory settings.
Etymology: The term 'millipoise' combines 'milli-', a prefix meaning one-thousandth, with 'poise', which honors the contributions of Jean Léonard Marie Poiseuille.
Current Use
Today, the millipoise is widely used in industries such as food processing, cosmetics, pharmaceuticals, and petrochemicals to determine the viscosity of various liquids. It is essential for quality control and formulation processes, allowing manufacturers to ensure that products maintain the desired texture and flow characteristics. The millipoise is particularly useful for testing low-viscosity fluids, where precise measurements are critical for product consistency and performance.
💡 Fun Facts
- •The millipoise is often used in laboratories to measure the viscosity of liquids in experiments and formulations.
- •Many common household products, such as shampoos and lotions, are formulated with specific viscosities measured in millipoise.
- •The viscosity of a fluid can change significantly with temperature, making it an important factor in product formulation.
