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.
NanostokesnSt
Target UnitThe nanostoke (symbol: nSt) is a unit of kinematic viscosity, which quantifies the internal resistance of a fluid to flow under the influence of gravity. One nanostoke is equivalent to 10^-9 stokes, where one stoke is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of 1 centipoise and a density of 1 g/cm³. This unit is useful for describing the properties of extremely low-viscosity fluids, particularly in the fields of microfluidics and nanotechnology.
Current Use
Nanostokes are widely used in fields such as microfluidics, where precise viscosity measurements are crucial for the design and operation of devices that manipulate fluids at the microscale. They are also relevant in biomedical applications, including the analysis of blood viscosity and the behavior of bodily fluids. Industries such as pharmaceuticals and materials science utilize nanostokes to characterize the flow properties of various substances.
Fun Fact
The term 'stokes' is often used in fluid dynamics and is a tribute to Sir George Gabriel Stokes, who made significant contributions to the field.

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.

viscosity • Non-SI
Definition
The nanostoke (symbol: nSt) is a unit of kinematic viscosity, which quantifies the internal resistance of a fluid to flow under the influence of gravity. One nanostoke is equivalent to 10^-9 stokes, where one stoke is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of 1 centipoise and a density of 1 g/cm³. This unit is useful for describing the properties of extremely low-viscosity fluids, particularly in the fields of microfluidics and nanotechnology.
History & Origin
The concept of viscosity dates back to the early studies of fluid mechanics, but the specific term 'stokes' was introduced in the late 19th century by the British scientist Sir George Gabriel Stokes. The nanostokes, being a subunit of stokes, was developed in the 20th century as the need for more precise measurements of fluid dynamics in small-scale applications emerged, particularly in the context of scientific research and industrial processes.
Etymology: The term 'nanostokes' combines the prefix 'nano-', meaning one billionth (10^-9), with 'stokes', named after Sir George Gabriel Stokes.
Current Use
Nanostokes are widely used in fields such as microfluidics, where precise viscosity measurements are crucial for the design and operation of devices that manipulate fluids at the microscale. They are also relevant in biomedical applications, including the analysis of blood viscosity and the behavior of bodily fluids. Industries such as pharmaceuticals and materials science utilize nanostokes to characterize the flow properties of various substances.
💡 Fun Facts
- •The term 'stokes' is often used in fluid dynamics and is a tribute to Sir George Gabriel Stokes, who made significant contributions to the field.
- •Nanostokes are particularly important in the emerging field of nanotechnology, where fluid behavior at the nanoscale can differ significantly from macro-scale behavior.
- •The viscosity of fluids can change dramatically with temperature, making precise measurements crucial in many scientific applications.
