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.
GigapoiseGPa
Target UnitThe gigapoise (GPa) is a unit of measurement for dynamic viscosity, representing one billion poise. Viscosity gauges a fluid's resistance to flow, and in this context, 1 gigapoise corresponds to 1,000,000,000 poise or 1,000 pascal-seconds (Pa·s). This unit is particularly used in high-viscosity fluids, where traditional units like poise or centipoise become impractical for expressing the magnitude of viscosity. It plays a crucial role in industries dealing with heavy oils, polymers, and other viscous materials, providing a clear understanding of the fluid's behavior under applied stress.
Current Use
Today, gigapoise is primarily used in industries that handle high-viscosity fluids, such as the petroleum, polymer, and food industries. It provides a standardized method for scientists and engineers to communicate the viscosity of substances that are otherwise difficult to quantify using smaller units. Its use spans across various applications, from formulating coatings and adhesives to analyzing the flow properties of polymers during manufacturing processes.
Fun Fact
The poise is named after Jean Poiseuille, who studied the flow of fluids through pipes.

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.
💡 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.

It plays a crucial role in industries dealing with heavy oils, polymers, and other viscous materials, providing a clear understanding of the fluid's behavior under applied stress.
History & Origin
The concept of viscosity has roots tracing back to the studies of fluid dynamics in the 19th century, notably introduced by scientists such as Sir Isaac Newton. The poise was named after French scientist Jean Léonard Marie Poiseuille, who studied fluid flow. The gigapoise, a derivative of this unit, was established to quantify extremely viscous fluids that require a larger scale for practical applications. Its adoption in scientific literature and industry has developed over the decades as material sciences have advanced.
Etymology: The term 'gigapoise' is derived from the prefix 'giga,' which denotes a factor of one billion, combined with 'poise,' named after the 19th-century physicist Jean Poiseuille.
