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.
FemtopoisefP
Target UnitThe femtopoise (fP) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, quantifying a fluid's resistance to flow. One femtopoise is equal to 10^-15 poise, a very small value indicating extremely low viscosity. Viscosity measures a fluid's internal friction, and thus its flow behavior. This measurement is crucial in various scientific and engineering applications, allowing for precise calculations in fluid dynamics and material sciences. A femtopoise is notably useful in fields that involve minuscule volumes or very low viscosity fluids, such as nanotechnology and biophysics.
Current Use
Femtopoise is predominantly used in specialized scientific research and high-tech industries where understanding fluid behavior at extremely low viscosities is critical. Industries such as pharmaceuticals, nanotechnology, and materials science utilize this measurement for characterizing novel fluids, colloids, and polymer solutions. Its application helps in the development of drug delivery systems, nanomaterials, and advanced lubricants, where precise viscosity control is essential for functionality and efficacy.
Fun Fact
The femtopoise is so small that it measures viscosities found in very specialized applications, often at the molecular level.

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

A femtopoise is notably useful in fields that involve minuscule volumes or very low viscosity fluids, such as nanotechnology and biophysics.
History & Origin
The concept of viscosity has been studied since the time of Newton, who defined it in 1687. The poise, named after French physicist Jean Léonard Marie Poiseuille, was introduced in the mid-19th century as a measure of dynamic viscosity. The femtopoise emerged as a subunit to represent extremely low viscosities encountered in various scientific fields, particularly as technologies evolved toward manipulating materials at the nanoscale. This development reflects the continuing need for more precise measurements in fluid dynamics, particularly in emerging fields.
Etymology: The term 'femto-' is derived from the Danish word 'femten', meaning 'fifteen', indicating the scale of 10^-15. 'Poise' originates from the name of Jean Léonard Marie Poiseuille, whose work in fluid dynamics laid the foundation for the measurement of viscosity.
Current Use
Femtopoise is predominantly used in specialized scientific research and high-tech industries where understanding fluid behavior at extremely low viscosities is critical.
