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.
KilostokeskSt
Target UnitThe kilostoke (kSt) is a unit of measure for kinematic viscosity, which is defined as the ratio of dynamic viscosity to fluid density. Specifically, one kilostoke is equal to 1,000 stokes, where one stoke is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of one centipoise and a density of one gram per cubic centimeter. Kinematic viscosity is crucial in various fluid dynamics applications, as it affects the flow behavior of fluids under the influence of gravity. The unit is commonly used in engineering and physics to characterize fluid properties.
Current Use
Today, the kilostoke is widely used in the petroleum industry, especially for measuring the viscosity of oils and lubricants. It is essential for determining the flow characteristics of fluids in pipelines, engines, and various manufacturing processes. Additionally, it finds applications in weather prediction models that simulate fluid movements in the atmosphere.
Fun Fact
The stoke is a rare example of a unit named after a person, highlighting the historical contributions to fluid dynamics.

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.

Kinematic viscosity is crucial in various fluid dynamics applications, as it affects the flow behavior of fluids under the influence of gravity. The unit is commonly used in engineering and physics to characterize fluid properties.
History & Origin
The kilostokes originated in the early 20th century, as scientists and engineers sought standardized measurements for fluid properties. The stoke was named after the British engineer Sir George Stokes, who made significant contributions to fluid dynamics and the study of viscosity. The kilostoke was established to quantify kinematic viscosity on a larger scale, facilitating calculations in various engineering applications.
Etymology: The term 'kilostokes' combines 'kilo', denoting a factor of one thousand, with 'stokes', named after Sir George Stokes, who contributed to the field of fluid dynamics.
Current Use
Today, the kilostoke is widely used in the petroleum industry, especially for measuring the viscosity of oils and lubricants. It is essential for determining the flow characteristics of fluids in pipelines, engines, and various manufacturing processes. Additionally, it finds applications in weather prediction models that simulate fluid movements in the atmosphere.
💡 Fun Facts
- •The stoke is a rare example of a unit named after a person, highlighting the historical contributions to fluid dynamics.
- •Kinematic viscosity is temperature-dependent, meaning the value can change significantly with temperature variations.
- •Many common fluids, like honey or syrup, exhibit high kinematic viscosity, making them ideal examples in educational settings.
