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.
KilostokeskSt
Target UnitThe kilostoke (kSt) is a unit of measure for kinematic viscosity, which is defined as the ratio of dynamic viscosity to fluid density. Specifically, one kilostoke is equal to 1,000 stokes, where one stoke is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of one centipoise and a density of one gram per cubic centimeter. Kinematic viscosity is crucial in various fluid dynamics applications, as it affects the flow behavior of fluids under the influence of gravity. The unit is commonly used in engineering and physics to characterize fluid properties.
Current Use
Today, the kilostoke is widely used in the petroleum industry, especially for measuring the viscosity of oils and lubricants. It is essential for determining the flow characteristics of fluids in pipelines, engines, and various manufacturing processes. Additionally, it finds applications in weather prediction models that simulate fluid movements in the atmosphere.
Fun Fact
The stoke is a rare example of a unit named after a person, highlighting the historical contributions to fluid dynamics.

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.
