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.
MegastokesmSt
Target UnitThe megastokes (mSt) is a non-SI unit of kinematic viscosity, representing the dynamic resistance of a fluid to flow under the influence of gravity. It is defined as one million stokes, where one stoke is equivalent to one square centimeter per second (cm²/s). This unit is particularly useful in describing the viscosity of highly viscous fluids, such as oils and heavy liquids, where precision in measurement is essential for applications in engineering and fluid mechanics. The use of megastokes allows for easier representation of large viscosity values.
Current Use
Megastokes is currently utilized in various industries, particularly in petrochemicals, lubricants, and food processing, where precise measurements of fluid viscosity are crucial. Engineers and scientists leverage this unit to characterize the flow behavior of thick liquids and emulsions. The megastokes unit is especially relevant in formulations where high viscosities can significantly impact processing and product performance. It is also used in research and development settings to evaluate new materials and their flow properties.
Fun Fact
The stoke unit was first introduced in 1851, making it one of the oldest viscosity units still in use today.

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.
