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.
PetastokesPSt
Target UnitThe petastokes (PSt) is a unit of dynamic viscosity in the CGS system, specifically equal to 10^15 stokes. It is used to quantify the internal resistance of fluids as they flow. In dynamic terms, viscosity measures a fluid's resistance to shear or flow under an applied force. This immense unit is primarily applicable in high-viscosity scenarios, often in specialized scientific and industrial contexts. One stoke is defined as the kinematic viscosity of a fluid with a dynamic viscosity of one centipoise and a density of one gram per cubic centimeter, making the petastokes a significant scale for analyzing extremely viscous materials.
Current Use
The petastokes is utilized primarily in specialized fields such as materials science, chemical engineering, and high-performance lubrication systems. Industries that deal with extremely viscous substances, such as polymers, petrochemicals, and some biopharmaceuticals, often use the petastokes to quantify viscosity levels accurately. It is particularly helpful when dealing with substances like heavy oils, molasses, and other thick fluids that exhibit significant resistance to flow.
Fun Fact
The petastokes is one of the largest units of viscosity available, used for measuring fluids that are exceptionally thick.

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.

History & Origin
The term 'stokes' originates from the name of the British scientist Sir George Gabriel Stokes, who contributed significantly to fluid dynamics in the 19th century. The petastokes, as a derivative unit, emerged as the need for measuring extremely high viscosities arose in scientific research and industrial applications, particularly in contexts such as polymer science and lubrication technology. The use of the petastokes allows researchers and engineers to communicate the properties of materials that exhibit exceptional viscosity levels.
