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.
FemtostokesfSt
Target UnitA femtostoke (fSt) is a unit of dynamic viscosity in the cgs (centimeter-gram-second) system, equivalent to 10^-15 stokes. The stoke is defined based on the kinematic viscosity of a fluid, where one stoke is the viscosity of a fluid with a density of 1 g/cm³ that has a kinematic viscosity of 1 cm²/s. Thus, femtostokes are used to express extremely low viscosities found in microfluidics and specialized applications, particularly in scientific research and advanced engineering.
Current Use
Femtostokes are currently used in cutting-edge research and applications where precise viscosity measurements at the nanoscale are required. This includes fields such as biomedical engineering, materials science, and nanotechnology, where understanding fluid behavior is crucial to innovation.
Fun Fact
The femtostoke is one of the smallest units of viscosity used in scientific research.

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
A femtostoke (fSt) is a unit of dynamic viscosity in the cgs (centimeter-gram-second) system, equivalent to 10^-15 stokes. The stoke is defined based on the kinematic viscosity of a fluid, where one stoke is the viscosity of a fluid with a density of 1 g/cm³ that has a kinematic viscosity of 1 cm²/s. Thus, femtostokes are used to express extremely low viscosities found in microfluidics and specialized applications, particularly in scientific research and advanced engineering.
History & Origin
The femtostoke was introduced in the late 20th century as scientific fields began to explore the properties of fluids at the microscale. As technology advanced, it became apparent that traditional units of viscosity were insufficient to quantify the extremely low viscosities encountered in new materials and experimental setups, leading to the need for smaller units like the femtostoke.
Etymology: The term 'femtostoke' combines 'femto-', a prefix in the metric system denoting a factor of 10^-15, with 'stoke,' named after the British engineer Sir George Stokes, who contributed to fluid dynamics.
Current Use
Femtostokes are currently used in cutting-edge research and applications where precise viscosity measurements at the nanoscale are required. This includes fields such as biomedical engineering, materials science, and nanotechnology, where understanding fluid behavior is crucial to innovation.
💡 Fun Facts
- •The femtostoke is one of the smallest units of viscosity used in scientific research.
- •Understanding fluid dynamics at this level can lead to breakthroughs in drug delivery technologies.
- •Femtostokes allow scientists to study fluid behaviors that were previously impossible to measure.
