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.
GigastokesGSt
Target UnitThe gigastokes (GSt) is a unit of kinematic viscosity in the CGS (centimeter-gram-second) system of units. It measures the internal resistance of a fluid to flow under the influence of gravity. One gigastokes is equivalent to 10^9 stokes, where one stoke is defined as the kinematic viscosity of a fluid in which a sphere of 1 cm radius falls through the fluid at a rate of 1 cm/s. This unit is particularly useful for measuring the viscosity of very low viscosity fluids or gases in scientific and engineering applications.
Current Use
Today, gigastokes are primarily used in industries that deal with fluids with very low viscosity, such as petrochemicals and synthetic lubricants. In these sectors, accurate viscosity measurements are essential for ensuring product performance and quality. The gigastokes unit allows engineers to quantify and communicate the behavior of these fluids under various temperature and pressure conditions, facilitating better design and operational efficiency.
Fun Fact
The stokes unit is equivalent to 10^-4 m²/s, making gigastokes a very large unit in comparison.

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.

Gigastokes
viscosity • Non-SI
Definition
The gigastokes (GSt) is a unit of kinematic viscosity in the CGS (centimeter-gram-second) system of units. It measures the internal resistance of a fluid to flow under the influence of gravity. One gigastokes is equivalent to 10^9 stokes, where one stoke is defined as the kinematic viscosity of a fluid in which a sphere of 1 cm radius falls through the fluid at a rate of 1 cm/s. This unit is particularly useful for measuring the viscosity of very low viscosity fluids or gases in scientific and engineering applications.
History & Origin
The term 'stokes' was named after Sir George Gabriel Stokes, a 19th-century Irish mathematician and physicist known for his work on fluid dynamics. The gigastokes is derived from this base unit, scaling it to encompass a broader range of viscosities encountered in various applications. The introduction of the gigastokes allowed for more manageable numerical representations of kinematic viscosity in high viscosity fluids that are otherwise cumbersome to express in standard stokes.
Etymology: The name 'gigastokes' combines the metric prefix 'giga-', meaning one billion (10^9), with 'stokes', named after Sir George Gabriel Stokes.
Current Use
Today, gigastokes are primarily used in industries that deal with fluids with very low viscosity, such as petrochemicals and synthetic lubricants. In these sectors, accurate viscosity measurements are essential for ensuring product performance and quality. The gigastokes unit allows engineers to quantify and communicate the behavior of these fluids under various temperature and pressure conditions, facilitating better design and operational efficiency.
💡 Fun Facts
- •The stokes unit is equivalent to 10^-4 m²/s, making gigastokes a very large unit in comparison.
- •In low viscosity applications, gigastokes values can be larger than most common fluids, highlighting the need for such a unit.
- •Sir George Stokes also contributed to the field of optics, demonstrating the diverse impact of his work across different scientific disciplines.
