Unit Explanations
Pascal SecondPa·s
Source UnitThe pascal second (Pa·s) is the SI unit for dynamic viscosity, representing the internal friction of fluids. It quantifies the resistance of a fluid to flow when an external force is applied. A fluid with a dynamic viscosity of one pascal second will flow under a shear stress of one pascal at a rate of one meter per second. It is a derived unit, meaning it is defined in terms of the base SI units: kilograms (kg), meters (m), and seconds (s). The pascal second is critical in fluid dynamics, engineering, and various scientific disciplines where fluid behavior is studied.
Current Use
Today, the pascal second is widely used in various industries including chemical engineering, food processing, and materials science to characterize the flow properties of fluids. It is essential in applications involving lubrication, mixing, and fluid transport where understanding viscosity is crucial for efficiency and safety.
Fun Fact
The pascal second is named after Blaise Pascal, who also has the unit of pressure named after him.
DekapoisedP
Target UnitThe dekapoise (dP) is a unit of dynamic viscosity, which quantifies a fluid's resistance to flow under applied stress. It is defined as 10 poise, where one poise is equivalent to 0.1 Pascal-seconds (Pa·s). This unit is often used in various industries to characterize the flow behavior of liquids, particularly in the food, cosmetics, and chemical sectors. The use of the dekapoise allows for easier expression of viscosity values that are significantly higher than typical measurements in poise, thus facilitating comparisons and assessments of fluid properties.
Current Use
Dekapoise is commonly used in industries where understanding fluid flow is essential, such as food processing, pharmaceuticals, and cosmetics. Laboratories often employ this unit when conducting rheological measurements, which assess how substances deform and flow under stress. The dekapoise facilitates communication of viscosity characteristics among engineers, scientists, and manufacturers, ensuring that specifications align with practical applications.
Fun Fact
The poise is named after Jean Léonard Marie Poiseuille, who is also known for his work in fluid dynamics.

viscosity • Non-SI
Definition
The pascal second (Pa·s) is the SI unit for dynamic viscosity, representing the internal friction of fluids. It quantifies the resistance of a fluid to flow when an external force is applied. A fluid with a dynamic viscosity of one pascal second will flow under a shear stress of one pascal at a rate of one meter per second. It is a derived unit, meaning it is defined in terms of the base SI units: kilograms (kg), meters (m), and seconds (s). The pascal second is critical in fluid dynamics, engineering, and various scientific disciplines where fluid behavior is studied.
History & Origin
The pascal second was introduced as part of the metric system in the late 20th century, named after Blaise Pascal, a French mathematician and physicist known for his contributions to fluid mechanics and pressure. The unit was formalized in 1971 during the 14th General Conference on Weights and Measures, which aimed to standardize units for scientific accuracy and international communication.
Etymology: The term 'pascal' is derived from the name of Blaise Pascal, while 'second' refers to the time unit in the SI system.
Current Use
Today, the pascal second is widely used in various industries including chemical engineering, food processing, and materials science to characterize the flow properties of fluids. It is essential in applications involving lubrication, mixing, and fluid transport where understanding viscosity is crucial for efficiency and safety.
💡 Fun Facts
- •The pascal second is named after Blaise Pascal, who also has the unit of pressure named after him.
- •Dynamic viscosity can change with temperature; for example, heating honey makes it flow more easily.
- •The viscosity of air is significantly lower than that of most liquids, making it easier for objects to move through it.

The use of the dekapoise allows for easier expression of viscosity values that are significantly higher than typical measurements in poise, thus facilitating comparisons and assessments of fluid properties.
History & Origin
The concept of viscosity has been studied since the time of Newton, who introduced the idea of a coefficient of viscosity in the early 18th century. The poise was named in honor of the French physicist Jean Léonard Marie Poiseuille, who studied the flow of fluids through pipes. The dekapoise was established as a convenient metric unit for measuring high viscosities, allowing scientists and engineers to express values that would otherwise be cumbersome in poise.
Etymology: The term 'dekapoise' combines the prefix 'deka-', meaning ten, with 'poise', named after Jean Léonard Marie Poiseuille.
