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/(cmĀ·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.
Newton Second Square MeterNĀ·sĀ·mĀ²
Target UnitThe newton second square meter (NĀ·sĀ·mĀ²) is a derived unit of dynamic viscosity in the International System of Units (SI). It quantifies the internal friction of a fluid, indicating how much resistance a fluid exhibits to flow under an applied force. Specifically, one newton second square meter is defined as the viscosity of a fluid that requires a force of one newton to maintain a velocity of one meter per second across a square meter area. This unit plays a crucial role in understanding fluid behavior in various applications, from engineering to environmental science.
Current Use
Today, the newton second square meter is widely used in various industries, including engineering, chemical processing, and environmental science, to measure the viscosity of fluids. It helps engineers and scientists understand how fluids behave under different conditions, facilitating the design of systems ranging from pipelines to chemical reactors. The unit is critical in applications involving lubrication, fluid transport, and material processing.
Fun Fact
The concept of viscosity was first introduced by Sir Isaac Newton in the 17th century.

viscosity ā¢ 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/(cmĀ·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.

Newton Second Square Meter
viscosity ā¢ Non-SI
Definition
The newton second square meter (NĀ·sĀ·mĀ²) is a derived unit of dynamic viscosity in the International System of Units (SI). It quantifies the internal friction of a fluid, indicating how much resistance a fluid exhibits to flow under an applied force. Specifically, one newton second square meter is defined as the viscosity of a fluid that requires a force of one newton to maintain a velocity of one meter per second across a square meter area. This unit plays a crucial role in understanding fluid behavior in various applications, from engineering to environmental science.
History & Origin
The newton second square meter originated from the work of Sir Isaac Newton in the late 17th century, who formulated the laws of motion and the concept of viscosity. His studies laid the groundwork for fluid dynamics, leading to the formal definition of viscosity. The unit was later formalized in the International System of Units as part of a broader movement to standardize measurement units across scientific disciplines.
Etymology: The term 'newton' is derived from the name of Sir Isaac Newton, while 'second' refers to the time unit and 'square meter' indicates area. Together, they reflect the relationship between force, time, and area in measuring viscosity.
Current Use
Today, the newton second square meter is widely used in various industries, including engineering, chemical processing, and environmental science, to measure the viscosity of fluids. It helps engineers and scientists understand how fluids behave under different conditions, facilitating the design of systems ranging from pipelines to chemical reactors. The unit is critical in applications involving lubrication, fluid transport, and material processing.
š” Fun Facts
- ā¢The concept of viscosity was first introduced by Sir Isaac Newton in the 17th century.
- ā¢Viscosity measurements can vary significantly with temperature; for instance, heating a fluid generally decreases its viscosity.
- ā¢The term 'viscosity' comes from the Latin word 'viscosus', meaning 'sticky' or 'tacky'.
