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.
Gram Centimeter Secondg·cm·s
Target UnitThe gram centimeter second (g·cm·s) is a non-SI unit of dynamic viscosity, which measures a fluid's resistance to flow. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when a shear rate of one reciprocal second is applied. This unit is particularly useful in various scientific and engineering contexts, allowing for consistent measurements of fluid behavior under shear. The gram centimeter second unit is derived from the base units of mass (grams), length (centimeters), and time (seconds), making it an intuitive choice for fluid mechanics.
Current Use
Today, the gram centimeter second unit remains widely employed in laboratories and industrial applications to quantify fluid viscosity. It is particularly prevalent in the fields of chemistry, engineering, and material science, where understanding fluid behavior is critical. Various industries, including food processing, petrochemicals, and pharmaceuticals, utilize this unit to ensure product consistency and quality.
Fun Fact
The viscosity of a fluid can change with temperature; for example, heating oil reduces its viscosity.

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 gram centimeter second unit is derived from the base units of mass (grams), length (centimeters), and time (seconds), making it an intuitive choice for fluid mechanics.
History & Origin
The concept of viscosity has roots in fluid mechanics, with early explorations dating back to ancient civilizations. The gram centimeter second unit arose during the metrication movement in the 18th century when scientists sought a standardized approach to measuring physical properties. The system gained traction in the 19th century as industrial processes required precise measurements of fluid dynamics for engineering applications.
Etymology: The term 'viscosity' derives from the Latin word 'viscosus,' meaning 'sticky' or 'thick,' indicating the resistance to flow of various fluids.
Current Use
Today, the gram centimeter second unit remains widely employed in laboratories and industrial applications to quantify fluid viscosity. It is particularly prevalent in the fields of chemistry, engineering, and material science, where understanding fluid behavior is critical. Various industries, including food processing, petrochemicals, and pharmaceuticals, utilize this unit to ensure product consistency and quality.
💡 Fun Facts
- •The viscosity of a fluid can change with temperature; for example, heating oil reduces its viscosity.
- •Water has a dynamic viscosity of about 1 g·cm·s at 20°C, making it a standard reference point.
- •The term 'stokes' is an alternative unit of kinematic viscosity, named after Sir George Gabriel Stokes.
