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.
Millinewton Second Square MetermN·s·m²
Target UnitA millinewton second square meter (mN·s·m²) is a unit of dynamic viscosity, measuring a fluid's resistance to flow. It represents the viscosity exerted by a force of one millinewton acting for one second on a square meter area. This unit is derived from the SI unit of viscosity, the pascal second (Pa·s), where 1 mN·s·m² equals 0.001 Pa·s. It quantifies how easily a fluid flows under stress, essential for various engineering and scientific applications, particularly in fluid dynamics, material science, and chemical processing.
Current Use
Millinewton seconds square meters are commonly used in laboratories and industries that deal with fluid dynamics, such as petrochemicals, pharmaceuticals, and food processing. Engineers often use this unit when designing systems that involve the flow of liquids and gases, ensuring that products meet specific viscosity requirements for optimal performance. Its application is critical in quality control processes and research and development of new materials.
Fun Fact
The unit millinewton is one-thousandth of a newton, making it useful for measuring very small forces.

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.

Millinewton Second Square Meter
viscosity • Non-SI
Definition
A millinewton second square meter (mN·s·m²) is a unit of dynamic viscosity, measuring a fluid's resistance to flow. It represents the viscosity exerted by a force of one millinewton acting for one second on a square meter area. This unit is derived from the SI unit of viscosity, the pascal second (Pa·s), where 1 mN·s·m² equals 0.001 Pa·s. It quantifies how easily a fluid flows under stress, essential for various engineering and scientific applications, particularly in fluid dynamics, material science, and chemical processing.
History & Origin
The concept of viscosity dates back to the 17th century when scientists began exploring fluid mechanics and material properties. The millinewton, a derived unit of force in the SI system, was defined later, with the newton being named after Sir Isaac Newton, who studied fluid motion. The combination of these units into millinewton seconds square meters for viscosity emerged from the need to measure the resistance of fluids more precisely, particularly in engineering applications.
Etymology: The term 'millinewton' is derived from the SI unit 'newton', named after Sir Isaac Newton, while 'second' refers to time, and 'square meter' is a unit of area.
