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.
Square Centimeter Secondcm²·s
Target UnitThe square centimeter second (cm²·s) is a unit of dynamic viscosity, which measures a fluid's resistance to flow. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when it flows with a velocity gradient of one centimeter per second. Dynamic viscosity reflects how thick or thin a fluid is, influencing the flow characteristics and behavior of liquids under various conditions. This unit is particularly relevant in fields such as fluid mechanics and engineering, where understanding fluid dynamics is crucial.
Current Use
Today, the square centimeter second is primarily used in fields such as chemical engineering, physics, and materials science, particularly in contexts where dynamic viscosity is a critical parameter. It is frequently encountered in laboratory settings for rheological testing of fluids and is used in industries such as paint, food, and petrochemicals to evaluate fluid characteristics. Despite the prevalence of SI units, cm²·s remains a familiar and practical choice in many scientific and engineering discussions, particularly in educational contexts.
Fun Fact
Honey's viscosity can vary greatly depending on its water content, often measured around 2.5 cm²·s.

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.

viscosity • Non-SI
Definition
The square centimeter second (cm²·s) is a unit of dynamic viscosity, which measures a fluid's resistance to flow. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when it flows with a velocity gradient of one centimeter per second. Dynamic viscosity reflects how thick or thin a fluid is, influencing the flow characteristics and behavior of liquids under various conditions. This unit is particularly relevant in fields such as fluid mechanics and engineering, where understanding fluid dynamics is crucial.
History & Origin
The square centimeter second originated from the centimeter-gram-second (CGS) system, which was developed in the 19th century. This system was widely used in scientific research and engineering before the adoption of the International System of Units (SI). The unit arose out of the need to quantify fluid viscosity in a way that was accessible and relatable, particularly in laboratory settings where measurements were often taken in centimeters and grams. As the understanding of fluid dynamics advanced, so too did the need for precise viscosity measurements, leading to the establishment of cm²·s as a standard unit.
Etymology: The term 'centimeter' derives from the Latin 'centum' (hundred) and the Greek 'metron' (measure), while 'second' reflects the time unit derived from the Latin 'secundus' (following). Together, they depict a measure of area and time, essential for understanding fluid flow characteristics.
Current Use
Today, the square centimeter second is primarily used in fields such as chemical engineering, physics, and materials science, particularly in contexts where dynamic viscosity is a critical parameter. It is frequently encountered in laboratory settings for rheological testing of fluids and is used in industries such as paint, food, and petrochemicals to evaluate fluid characteristics. Despite the prevalence of SI units, cm²·s remains a familiar and practical choice in many scientific and engineering discussions, particularly in educational contexts.
💡 Fun Facts
- •Honey's viscosity can vary greatly depending on its water content, often measured around 2.5 cm²·s.
- •The viscosity of blood at 37°C is approximately 3.5 cm²·s, significantly affecting circulation.
- •The term 'viscosity' is derived from the Latin 'viscosus', meaning 'sticky' or 'thick'.
