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.
Dyne Second per Square Centimeterdyn·s/cm²
Target UnitThe dyne second per square centimeter (dyn·s/cm²) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It quantifies the internal frictional resistance of a fluid to flow. Specifically, one dyne second per square centimeter is defined as the viscosity of a fluid that, when subjected to a shear stress of one dyne per square centimeter, will yield a velocity gradient of one reciprocal second. This unit is crucial in characterizing fluid dynamics and is particularly significant in fields such as engineering and physics, where the behavior of fluids under various conditions is analyzed.
Current Use
The dyne second per square centimeter is still utilized in various scientific and engineering contexts, particularly in the study of fluid mechanics, material science, and rheology. Industries such as petrochemicals, pharmaceuticals, and food processing frequently employ this unit to measure the viscosity of liquids and slurries. It helps engineers design equipment that involves the flow of fluids, ensuring optimal performance and safety. Furthermore, educational institutions often use this unit to teach fundamental principles of fluid dynamics, making it a staple in physics and engineering curricula.
Fun Fact
The dyne is a part of the CGS system, which is less commonly used today but historically significant.

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.

Dyne Second per Square Centimeter
viscosity • Non-SI
Definition
The dyne second per square centimeter (dyn·s/cm²) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It quantifies the internal frictional resistance of a fluid to flow. Specifically, one dyne second per square centimeter is defined as the viscosity of a fluid that, when subjected to a shear stress of one dyne per square centimeter, will yield a velocity gradient of one reciprocal second. This unit is crucial in characterizing fluid dynamics and is particularly significant in fields such as engineering and physics, where the behavior of fluids under various conditions is analyzed.
History & Origin
The dyne second per square centimeter has its roots in the CGS system, which emerged in the 19th century as a practical alternative to the metric system. The CGS system was developed to facilitate scientific measurements and calculations, especially in fields like physics and engineering, where the behavior of fluids is critical. The unit of dyne itself is derived from the force required to accelerate a mass of one gram at a rate of one centimeter per second squared, establishing a connection between mass, distance, and time. This unit's use in viscosity measurement became widespread as researchers sought standardized methods for quantifying fluid resistance.
Etymology: The term 'dyne' comes from the Greek word 'dunamis', meaning 'force', while 'second' and 'centimeter' are derived from the Latin 'secundus' meaning 'second' and the French 'centi' meaning 'one-hundredth'.
Current Use
The dyne second per square centimeter is still utilized in various scientific and engineering contexts, particularly in the study of fluid mechanics, material science, and rheology. Industries such as petrochemicals, pharmaceuticals, and food processing frequently employ this unit to measure the viscosity of liquids and slurries. It helps engineers design equipment that involves the flow of fluids, ensuring optimal performance and safety. Furthermore, educational institutions often use this unit to teach fundamental principles of fluid dynamics, making it a staple in physics and engineering curricula.
💡 Fun Facts
- •The dyne is a part of the CGS system, which is less commonly used today but historically significant.
- •Viscosity measurements can vary with temperature; for example, heating a fluid typically reduces its viscosity.
- •The term 'viscosity' comes from the Latin 'viscosus', meaning sticky or adhesive.
