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.
PetastokesPSt
Target UnitThe petastokes (PSt) is a unit of dynamic viscosity in the CGS system, specifically equal to 10^15 stokes. It is used to quantify the internal resistance of fluids as they flow. In dynamic terms, viscosity measures a fluid's resistance to shear or flow under an applied force. This immense unit is primarily applicable in high-viscosity scenarios, often in specialized scientific and industrial contexts. One stoke is defined as the kinematic viscosity of a fluid with a dynamic viscosity of one centipoise and a density of one gram per cubic centimeter, making the petastokes a significant scale for analyzing extremely viscous materials.
Current Use
The petastokes is utilized primarily in specialized fields such as materials science, chemical engineering, and high-performance lubrication systems. Industries that deal with extremely viscous substances, such as polymers, petrochemicals, and some biopharmaceuticals, often use the petastokes to quantify viscosity levels accurately. It is particularly helpful when dealing with substances like heavy oils, molasses, and other thick fluids that exhibit significant resistance to flow.
Fun Fact
The petastokes is one of the largest units of viscosity available, used for measuring fluids that are exceptionally thick.

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.

One stoke is defined as the kinematic viscosity of a fluid with a dynamic viscosity of one centipoise and a density of one gram per cubic centimeter, making the petastokes a significant scale for analyzing extremely viscous materials.
History & Origin
The term 'stokes' originates from the name of the British scientist Sir George Gabriel Stokes, who contributed significantly to fluid dynamics in the 19th century. The petastokes, as a derivative unit, emerged as the need for measuring extremely high viscosities arose in scientific research and industrial applications, particularly in contexts such as polymer science and lubrication technology. The use of the petastokes allows researchers and engineers to communicate the properties of materials that exhibit exceptional viscosity levels.
