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.
HectostokeshSt
Target UnitA hectostokes (hSt) is a unit of measurement for kinematic viscosity, defined as the ratio of dynamic viscosity to fluid density. Specifically, one hectostokes is equal to 100 centistokes (cSt), where 1 cSt is equivalent to 1 mm²/s. This unit is commonly used in the field of fluid dynamics and lubrication engineering, providing a standard measure of how a fluid flows under the influence of gravity. The use of hectostokes simplifies the representation of viscosity values for liquids, particularly in industrial applications.
Current Use
Hectostokes is commonly used in industries such as petrochemicals, food processing, and pharmaceuticals, where understanding the flow properties of fluids is essential. It is particularly useful in quality control, ensuring that products meet the necessary viscosity specifications for processing and application. Laboratories and research institutions also utilize hectostokes for accurate scientific assessments of fluid behavior.
Fun Fact
The stokes unit is often considered an 'antique' unit of measurement in modern 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.
💡 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.

History & Origin
The hectostokes unit was derived from the stoke (St), named after the British engineer Sir George Stokes. The stoke itself was established in the late 19th century as a measure of kinematic viscosity, and its derivatives, including hectostokes, have gained popularity in various scientific and engineering contexts. The introduction of the centistoke (cSt) simplified the measurement of viscosity for many practical applications, leading to the adoption of hectostokes as a larger unit for ease of use.
Etymology: The term 'hecto' originates from the Greek word 'hekaton,' meaning one hundred, while 'stokes' refers to Sir George Stokes, who contributed significantly to fluid dynamics.
