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.
Square Meter Secondm²·s
Target UnitThe square meter second (m²·s) is a derived unit of dynamic viscosity in the International System of Units (SI). It represents the measure of a fluid's resistance to flow, specifically quantifying how easily a fluid can deform under shear stress. One m²·s indicates that one square meter of surface area experiences a shear force of one Newton per square meter for one second. This unit is particularly relevant in fluid dynamics and engineering, where understanding the flow characteristics of various liquids and gases is essential.
Current Use
Square meter second is widely used in various industries such as oil and gas, food and beverage, and pharmaceuticals, where the viscosity of fluids is critical to process design and quality control. Engineers and scientists use this unit to ensure that liquids can flow properly under specific conditions, optimizing processes like mixing, pumping, and transport. It's also essential in research settings for characterizing new materials and formulations.
Fun Fact
The viscosity of honey can be up to 100 times greater than that of water.

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.

Square Meter Second
viscosity • Non-SI
Definition
The square meter second (m²·s) is a derived unit of dynamic viscosity in the International System of Units (SI). It represents the measure of a fluid's resistance to flow, specifically quantifying how easily a fluid can deform under shear stress. One m²·s indicates that one square meter of surface area experiences a shear force of one Newton per square meter for one second. This unit is particularly relevant in fluid dynamics and engineering, where understanding the flow characteristics of various liquids and gases is essential.
History & Origin
The square meter second emerged from the need to measure fluid viscosity and is rooted in the definitions of fundamental SI units. The concept of viscosity itself dates back to the early studies of fluid mechanics in the 17th century. Notably, Sir Isaac Newton's work laid the groundwork for understanding viscous flow, leading to the formalization of viscosity as a measurable property of fluids. The adoption of SI units in the 20th century standardized the measurement of dynamic viscosity, culminating in the square meter second as a recognized unit.
Etymology: The term 'viscosity' derives from the Latin 'viscosus', meaning sticky or thick.
Current Use
Square meter second is widely used in various industries such as oil and gas, food and beverage, and pharmaceuticals, where the viscosity of fluids is critical to process design and quality control. Engineers and scientists use this unit to ensure that liquids can flow properly under specific conditions, optimizing processes like mixing, pumping, and transport. It's also essential in research settings for characterizing new materials and formulations.
💡 Fun Facts
