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.
Square Meter Secondm²·s
Target UnitThe square meter second (m²·s) is a derived unit of dynamic viscosity in the International System of Units (SI). It represents the measure of a fluid's resistance to flow, specifically quantifying how easily a fluid can deform under shear stress. One m²·s indicates that one square meter of surface area experiences a shear force of one Newton per square meter for one second. This unit is particularly relevant in fluid dynamics and engineering, where understanding the flow characteristics of various liquids and gases is essential.
Current Use
Square meter second is widely used in various industries such as oil and gas, food and beverage, and pharmaceuticals, where the viscosity of fluids is critical to process design and quality control. Engineers and scientists use this unit to ensure that liquids can flow properly under specific conditions, optimizing processes like mixing, pumping, and transport. It's also essential in research settings for characterizing new materials and formulations.
Fun Fact
The viscosity of honey can be up to 100 times greater than that of water.

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 square meter second emerged from the need to measure fluid viscosity and is rooted in the definitions of fundamental SI units. The concept of viscosity itself dates back to the early studies of fluid mechanics in the 17th century. Notably, Sir Isaac Newton's work laid the groundwork for understanding viscous flow, leading to the formalization of viscosity as a measurable property of fluids. The adoption of SI units in the 20th century standardized the measurement of dynamic viscosity, culminating in the square meter second as a recognized unit.
Etymology: The term 'viscosity' derives from the Latin 'viscosus', meaning sticky or thick.
