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.
TerastokesTst
Target UnitThe terastokes (Tst) is a non-SI unit of dynamic viscosity, which is equal to 10^12 stokes (St). The stoke itself is defined as the kinematic viscosity of a fluid with a dynamic viscosity of 1 centipoise (cP) and a specific gravity of 1. The terastokes is typically used in contexts where extremely high viscosity values are encountered, such as in specialized industrial applications or theoretical computations in fluid dynamics. This unit allows for the expression of large viscosity values in a more manageable format, facilitating easier communication and calculation.
Current Use
The terastokes is primarily used in specialized fields such as petrochemicals, lubricants, and advanced fluid dynamics research. In these industries, fluids can exhibit extremely high viscosity values, necessitating the use of large units like the terastokes to simplify calculations and descriptions of fluid behavior. Laboratories and industrial plants often refer to terastokes when dealing with highly viscous substances like heavy oils or polymer solutions.
Fun Fact
The stoke, and by extension the terastokes, is named after George Stokes, who also contributed to the field of optics.

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.

History & Origin
The concept of viscosity dates back to the early studies of fluid mechanics, with significant contributions from scientists like Sir Isaac Newton and George Stokes in the 19th century. The stoke was named after Stokes, who formulated the laws of viscosity and described how fluids resist flow. The terastokes, being a multiple of the stoke, was introduced to quantify extremely viscous fluids, particularly in the petroleum and chemical industries, where conventional units may fall short.
Etymology: The term 'terastokes' derives from the prefix 'tera-' meaning trillion, combined with 'stokes' which honors the physicist George Stokes who significantly advanced the understanding of fluid mechanics.
Current Use
The terastokes is primarily used in specialized fields such as petrochemicals, lubricants, and advanced fluid dynamics research. In these industries, fluids can exhibit extremely high viscosity values, necessitating the use of large units like the terastokes to simplify calculations and descriptions of fluid behavior.

- •The stoke, and by extension the terastokes, is named after George Stokes, who also contributed to the field of optics.
- •In fluid dynamics, viscosity is a critical factor in determining whether a flow is laminar or turbulent.
- •The terastokes is rarely encountered in everyday situations; it is primarily used in specialized scientific and industrial contexts.
