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.
PetapoiseP
Target UnitThe petapoise (P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, equivalent to 10^15 poise. Viscosity quantifies a fluid's resistance to flow and deformation. This unit is primarily used to express the viscosity of extremely viscous substances, such as certain gels and heavy oils, where traditional units are insufficient. Viscosity is essential in various scientific and industrial applications, influencing processes like lubrication, mixing, and heat transfer.
Current Use
The petapoise is primarily used in sectors dealing with highly viscous fluids. It is especially common in research and development of new materials, such as polymers, adhesives, and specialty chemicals, where understanding flow characteristics is essential. Industries such as oil and gas, pharmaceuticals, and food processing utilize this unit to assess the behavior of heavy oils, gels, and other viscous products during processing and application.
Fun Fact
The poise is named after Jean Louis Marie Poiseuille, who studied fluid flow in tubes.

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.

Petapoise
viscosity • Non-SI
Definition
The petapoise (P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, equivalent to 10^15 poise. Viscosity quantifies a fluid's resistance to flow and deformation. This unit is primarily used to express the viscosity of extremely viscous substances, such as certain gels and heavy oils, where traditional units are insufficient. Viscosity is essential in various scientific and industrial applications, influencing processes like lubrication, mixing, and heat transfer.
History & Origin
The petapoise was introduced in the mid-20th century as a way to quantify the viscosity of extremely thick fluids. It emerged from the need to measure the properties of materials that could not be adequately described using smaller units of poise, which were more common at the time. As technologies advanced, particularly in chemical engineering and material science, the need for larger units became apparent, leading to the adoption of the petapoise.
Etymology: The term 'petapoise' is derived from the prefix 'peta-', which denotes a factor of 10^15, combined with 'poise', named after the French physicist Jean Louis Marie Poiseuille, who contributed significantly to fluid dynamics.
Current Use
The petapoise is primarily used in sectors dealing with highly viscous fluids. It is especially common in research and development of new materials, such as polymers, adhesives, and specialty chemicals, where understanding flow characteristics is essential. Industries such as oil and gas, pharmaceuticals, and food processing utilize this unit to assess the behavior of heavy oils, gels, and other viscous products during processing and application.
💡 Fun Facts
- •The poise is named after Jean Louis Marie Poiseuille, who studied fluid flow in tubes.
- •One petapoise is equivalent to the viscosity of a fluid that is 1,000,000 times thicker than water.
- •The petapoise is rarely encountered in everyday applications due to its large scale, typically reserved for specialized industrial contexts.
