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 Inch Secondin²·s
Target UnitThe square inch second (in²·s) is a unit of dynamic viscosity used primarily in the imperial system. It quantifies a fluid's resistance to flow and is defined as the viscosity of a fluid which, under a shear stress of one pound per square inch, produces a shear rate of one reciprocal second. This unit is often used in fields like engineering and fluid mechanics, providing insight into how fluids behave under various conditions, particularly in lubrication applications and material processing.
Current Use
The square inch second is utilized primarily in industries that require precise measurements of fluid viscosity, such as petroleum, food processing, and pharmaceuticals. It is particularly relevant in contexts where fluids are subjected to shear stress, such as in hydraulic systems and lubrication technology, allowing engineers to design systems that operate efficiently under varying conditions.
Fun Fact
The viscosity of most fluids decreases with increasing temperature.

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.

This unit is often used in fields like engineering and fluid mechanics, providing insight into how fluids behave under various conditions, particularly in lubrication applications and material processing.
History & Origin
The concept of viscosity dates back to the early studies of fluid mechanics, with the square inch second emerging as a specific unit in the context of the imperial measurement system. Its use became more widespread in the 19th century as industrial processes involving fluids became more complex, necessitating precise measurements of fluid behavior.
Etymology: The term 'viscosity' is derived from the Latin word 'viscosus', meaning 'sticky' or 'tacky', describing the resistance of a fluid to flow.
Current Use
The square inch second is utilized primarily in industries that require precise measurements of fluid viscosity, such as petroleum, food processing, and pharmaceuticals. It is particularly relevant in contexts where fluids are subjected to shear stress, such as in hydraulic systems and lubrication technology, allowing engineers to design systems that operate efficiently under varying conditions.
💡 Fun Facts
- •The viscosity of most fluids decreases with increasing temperature.
- •Honey can have a viscosity as high as 10,000 in²·s at room temperature.
- •The concept of viscosity was first introduced by Sir Isaac Newton in his work on fluid mechanics.
