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.
DekastokesdSt
Target UnitThe dekastokes is a unit of dynamic viscosity in the centistokes scale, equivalent to 10 Stokes. It is used to express the internal frictional resistance of fluids under shear stress, where higher values indicate greater viscosity. In the SI unit system, viscosity is typically measured in pascal-seconds (Pa·s), but the Stokes and its multiples, such as the dekastokes, are commonly used in various industries. The unit is crucial for characterizing the flow behavior of liquids, particularly in engineering and scientific applications.
Current Use
Dekastokes are widely utilized in the petroleum and chemical industries to assess the viscosity of oils, fuels, and other fluids. They are essential in quality control processes, ensuring that products meet specific viscosity standards for optimal performance. Additionally, dekastokes are used in research and development to evaluate and compare the flow characteristics of various fluids, making them valuable in both laboratory and industrial settings.
Fun Fact
The Stokes unit is named after Sir George Gabriel Stokes, who formulated the Stokes flow equations.

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.
