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.
Pound Force Second per Square Footlbf·s/ft²
Target UnitThe pound force second per square foot (lbf·s/ft²) is a unit of dynamic viscosity in the imperial system, quantifying the resistance of a fluid to flow. It refers to the force in pounds exerted over a unit area in square feet, multiplied by the time in seconds. This measurement is particularly relevant in fluid dynamics, as it combines mass, length, and time dimensions to describe how a fluid flows under applied forces. It serves as a crucial indicator in various applications, from engineering to physics.
Current Use
Today, the pound force second per square foot is widely utilized in engineering, particularly within the oil and gas, automotive, and chemical industries. It provides a practical measure for calculating the viscosity of fluids used in various processes, such as lubrication, transportation, and chemical reactions. Engineers rely on this unit to design systems that efficiently handle and manipulate fluids, ensuring optimal performance in machinery and manufacturing.
Fun Fact
The concept of viscosity is crucial for understanding how different liquids flow, impacting everything from cooking to industrial processes.

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.
