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.
Kilogram Force Second Square Meterkgf·s·m²
Target UnitThe kilogram force second square meter (kgf·s·m²) is a unit that quantifies dynamic viscosity, an essential property in fluid mechanics and material science. It is derived from the force exerted on a surface area over time, where 1 kgf represents the force exerted by a mass of 1 kilogram under standard gravity. This unit is particularly useful in engineering applications, allowing for the assessment of how fluids behave under various conditions, such as in pipelines or during manufacturing processes. The kgf·s·m² provides a clear representation of a fluid's resistance to flow and deformation.
Current Use
The kilogram force second square meter is used primarily in engineering fields, particularly in fluid dynamics and materials science. It serves as a critical parameter in evaluating how different liquids behave under various conditions, including temperature and pressure. Industries that utilize this unit include petroleum, automotive, and manufacturing, where understanding fluid dynamics is crucial for optimizing processes and product quality.
Fun Fact
The concept of viscosity was first introduced by Sir Isaac Newton in the late 17th century.

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.

The kgf·s·m² provides a clear representation of a fluid's resistance to flow and deformation.
History & Origin
The kilogram force second square meter unit originated from the need to characterize fluid behavior under applied forces. The combination of mass, force, and area allows for a practical understanding of viscosity in various contexts. The use of kilograms and seconds reflects the customary units in physics and engineering, providing a direct measurement of how much force is required to move a fluid over a given area and time.
Etymology: The term 'kilogram' comes from the French word 'kilogramme', itself derived from 'kilo-' meaning a thousand, and 'gramme', a small weight. 'Force' is derived from Latin 'fortis', meaning strong, while 'second' originates from the Latin 'secundus', meaning following, and 'meter' from Greek 'metron', meaning measure.
Current Use
The kilogram force second square meter is used primarily in engineering fields, particularly in fluid dynamics and materials science. It serves as a critical parameter in evaluating how different liquids behave under various conditions, including temperature and pressure.
