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.
PetapoiseP
Target UnitThe petapoise (P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, equivalent to 10^15 poise. Viscosity quantifies a fluid's resistance to flow and deformation. This unit is primarily used to express the viscosity of extremely viscous substances, such as certain gels and heavy oils, where traditional units are insufficient. Viscosity is essential in various scientific and industrial applications, influencing processes like lubrication, mixing, and heat transfer.
Current Use
The petapoise is primarily used in sectors dealing with highly viscous fluids. It is especially common in research and development of new materials, such as polymers, adhesives, and specialty chemicals, where understanding flow characteristics is essential. Industries such as oil and gas, pharmaceuticals, and food processing utilize this unit to assess the behavior of heavy oils, gels, and other viscous products during processing and application.
Fun Fact
The poise is named after Jean Louis Marie Poiseuille, who studied fluid flow in tubes.

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.

Petapoise
viscosity • Non-SI
Definition
The petapoise (P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, equivalent to 10^15 poise. Viscosity quantifies a fluid's resistance to flow and deformation. This unit is primarily used to express the viscosity of extremely viscous substances, such as certain gels and heavy oils, where traditional units are insufficient. Viscosity is essential in various scientific and industrial applications, influencing processes like lubrication, mixing, and heat transfer.
History & Origin
The petapoise was introduced in the mid-20th century as a way to quantify the viscosity of extremely thick fluids. It emerged from the need to measure the properties of materials that could not be adequately described using smaller units of poise, which were more common at the time. As technologies advanced, particularly in chemical engineering and material science, the need for larger units became apparent, leading to the adoption of the petapoise.
Etymology: The term 'petapoise' is derived from the prefix 'peta-', which denotes a factor of 10^15, combined with 'poise', named after the French physicist Jean Louis Marie Poiseuille, who contributed significantly to fluid dynamics.
Current Use
The petapoise is primarily used in sectors dealing with highly viscous fluids. It is especially common in research and development of new materials, such as polymers, adhesives, and specialty chemicals, where understanding flow characteristics is essential.

💡 Fun Facts
- •The poise is named after Jean Louis Marie Poiseuille, who studied fluid flow in tubes.
- •One petapoise is equivalent to the viscosity of a fluid that is 1,000,000 times thicker than water.
- •The petapoise is rarely encountered in everyday applications due to its large scale, typically reserved for specialized industrial contexts.
