Unit Explanations
Pascal SecondPaĀ·s
Source UnitThe pascal second (PaĀ·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.
Newton Second Square MeterNĀ·sĀ·mĀ²
Target UnitThe newton second square meter (NĀ·sĀ·mĀ²) is a derived unit of dynamic viscosity in the International System of Units (SI). It quantifies the internal friction of a fluid, indicating how much resistance a fluid exhibits to flow under an applied force. Specifically, one newton second square meter is defined as the viscosity of a fluid that requires a force of one newton to maintain a velocity of one meter per second across a square meter area. This unit plays a crucial role in understanding fluid behavior in various applications, from engineering to environmental science.
Current Use
Today, the newton second square meter is widely used in various industries, including engineering, chemical processing, and environmental science, to measure the viscosity of fluids. It helps engineers and scientists understand how fluids behave under different conditions, facilitating the design of systems ranging from pipelines to chemical reactors. The unit is critical in applications involving lubrication, fluid transport, and material processing.
Fun Fact
The concept of viscosity was first introduced by Sir Isaac Newton in the 17th century.

Definition
The pascal second (PaĀ·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
