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.
FemtopoisefP
Target UnitThe femtopoise (fP) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, quantifying a fluid's resistance to flow. One femtopoise is equal to 10^-15 poise, a very small value indicating extremely low viscosity. Viscosity measures a fluid's internal friction, and thus its flow behavior. This measurement is crucial in various scientific and engineering applications, allowing for precise calculations in fluid dynamics and material sciences. A femtopoise is notably useful in fields that involve minuscule volumes or very low viscosity fluids, such as nanotechnology and biophysics.
Current Use
Femtopoise is predominantly used in specialized scientific research and high-tech industries where understanding fluid behavior at extremely low viscosities is critical. Industries such as pharmaceuticals, nanotechnology, and materials science utilize this measurement for characterizing novel fluids, colloids, and polymer solutions. Its application helps in the development of drug delivery systems, nanomaterials, and advanced lubricants, where precise viscosity control is essential for functionality and efficacy.
Fun Fact
The femtopoise is so small that it measures viscosities found in very specialized applications, often at the molecular level.

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.

Definition
The femtopoise (fP) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, quantifying a fluid's resistance to flow. One femtopoise is equal to 10^-15 poise, a very small value indicating extremely low viscosity. Viscosity measures a fluid's internal friction, and thus its flow behavior.

A femtopoise is notably useful in fields that involve minuscule volumes or very low viscosity fluids, such as nanotechnology and biophysics.
History & Origin
The concept of viscosity has been studied since the time of Newton, who defined it in 1687. The poise, named after French physicist Jean Léonard Marie Poiseuille, was introduced in the mid-19th century as a measure of dynamic viscosity. The femtopoise emerged as a subunit to represent extremely low viscosities encountered in various scientific fields, particularly as technologies evolved toward manipulating materials at the nanoscale. This development reflects the continuing need for more precise measurements in fluid dynamics, particularly in emerging fields.
Etymology: The term 'femto-' is derived from the Danish word 'femten', meaning 'fifteen', indicating the scale of 10^-15. 'Poise' originates from the name of Jean Léonard Marie Poiseuille, whose work in fluid dynamics laid the foundation for the measurement of viscosity.
Current Use
Femtopoise is predominantly used in specialized scientific research and high-tech industries where understanding fluid behavior at extremely low viscosities is critical. Industries such as pharmaceuticals, nanotechnology, and materials science utilize this measurement for characterizing novel fluids, colloids, and polymer solutions.
