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.
PicopoisepP
Target UnitThe picopoise (pP) is a subunit of the poise, a unit of dynamic viscosity in the centimeter-gram-second (CGS) system. It measures a fluid's resistance to flow and is defined as one trillionth of a poise, where one poise is equal to one gram per centimeter-second. The picopoise is particularly useful in describing the viscosity of very low-viscosity fluids, such as certain biological fluids and light oils, making it applicable in a variety of scientific and engineering contexts.
Current Use
Picopoise is primarily used in laboratory settings to measure the viscosity of low-viscosity fluids, such as biological fluids, inks, and coatings. It is essential in industries that require precise fluid dynamics, such as pharmaceuticals, food science, and nanotechnology.
Fun Fact
The picopoise is often used in the context of fluids that can change viscosity with temperature, such as oils.

Poise
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.

Picopoise
viscosity • Non-SI
Definition
The picopoise (pP) is a subunit of the poise, a unit of dynamic viscosity in the centimeter-gram-second (CGS) system. It measures a fluid's resistance to flow and is defined as one trillionth of a poise, where one poise is equal to one gram per centimeter-second. The picopoise is particularly useful in describing the viscosity of very low-viscosity fluids, such as certain biological fluids and light oils, making it applicable in a variety of scientific and engineering contexts.
History & Origin
The concept of viscosity dates back to the 19th century, with the poise being named after the French physicist Jean Louis Marie Poiseuille, who studied fluid flow in the 1840s. The picopoise was introduced as part of the metric system's expansion to allow for measurements of extremely low viscosities, particularly relevant in fields like biology and materials science.
Etymology: The term 'picopoise' combines 'pico-', a metric prefix denoting one trillionth (10^-12), with 'poise', named after Jean Louis Marie Poiseuille.
Current Use
Picopoise is primarily used in laboratory settings to measure the viscosity of low-viscosity fluids, such as biological fluids, inks, and coatings. It is essential in industries that require precise fluid dynamics, such as pharmaceuticals, food science, and nanotechnology.
💡 Fun Facts
- •The picopoise is often used in the context of fluids that can change viscosity with temperature, such as oils.
- •In the field of nanotechnology, measuring viscosity in picopoise can be crucial for the development of new materials.
- •The use of picopoise allows scientists to accurately describe the flow characteristics of fluids in microfluidic devices.
