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.
Millinewton Second Square MetermN·s·m²
Target UnitA millinewton second square meter (mN·s·m²) is a unit of dynamic viscosity, measuring a fluid's resistance to flow. It represents the viscosity exerted by a force of one millinewton acting for one second on a square meter area. This unit is derived from the SI unit of viscosity, the pascal second (Pa·s), where 1 mN·s·m² equals 0.001 Pa·s. It quantifies how easily a fluid flows under stress, essential for various engineering and scientific applications, particularly in fluid dynamics, material science, and chemical processing.
Current Use
Millinewton seconds square meters are commonly used in laboratories and industries that deal with fluid dynamics, such as petrochemicals, pharmaceuticals, and food processing. Engineers often use this unit when designing systems that involve the flow of liquids and gases, ensuring that products meet specific viscosity requirements for optimal performance. Its application is critical in quality control processes and research and development of new materials.
Fun Fact
The unit millinewton is one-thousandth of a newton, making it useful for measuring very small forces.

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.

Millinewton Second Square Meter
viscosity • Non-SI
Definition
A millinewton second square meter (mN·s·m²) is a unit of dynamic viscosity, measuring a fluid's resistance to flow. It represents the viscosity exerted by a force of one millinewton acting for one second on a square meter area. This unit is derived from the SI unit of viscosity, the pascal second (Pa·s), where 1 mN·s·m² equals 0.001 Pa·s. It quantifies how easily a fluid flows under stress, essential for various engineering and scientific applications, particularly in fluid dynamics, material science, and chemical processing.
History & Origin
The concept of viscosity dates back to the 17th century when scientists began exploring fluid mechanics and material properties. The millinewton, a derived unit of force in the SI system, was defined later, with the newton being named after Sir Isaac Newton, who studied fluid motion. The combination of these units into millinewton seconds square meters for viscosity emerged from the need to measure the resistance of fluids more precisely, particularly in engineering applications.
Etymology: The term 'millinewton' is derived from the SI unit 'newton', named after Sir Isaac Newton, while 'second' refers to time, and 'square meter' is a unit of area.
Current Use
Millinewton seconds square meters are commonly used in laboratories and industries that deal with fluid dynamics, such as petrochemicals, pharmaceuticals, and food processing. Engineers often use this unit when designing systems that involve the flow of liquids and gases, ensuring that products meet specific viscosity requirements for optimal performance. Its application is critical in quality control processes and research and development of new materials.
💡 Fun Facts
- •The unit millinewton is one-thousandth of a newton, making it useful for measuring very small forces.
- •Dynamic viscosity is temperature-dependent; as temperature increases, viscosity generally decreases.
- •The study of viscosity has practical applications in various fields, including meteorology, where it helps in predicting weather patterns.
