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.
TerapoiseTPa
Target UnitThe terapoise (TPa) is a derived unit of dynamic viscosity in the metric system, representing a measure of a fluid's resistance to flow. It is defined as 10^12 poise, where one poise is equivalent to one gram per centimeter per second (g/(cm·s)). The terapoise is used in specialized scientific and engineering applications where extremely high viscosity values are encountered, such as in the study of certain polymer solutions and heavy oils. This unit provides a convenient way to express very large viscosity measurements without resorting to exponential notation.
Current Use
The terapoise is predominantly used in scientific research and industrial applications where extremely high viscosity fluids are analyzed. Industries such as petroleum, polymers, and food processing may utilize this unit to assess the flow characteristics of materials. However, its application is mainly restricted to laboratories as standard industrial measurements typically do not reach such high viscosity levels.
Fun Fact
The terapoise is rarely encountered in everyday applications, as most fluids have much lower viscosities.

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.

This unit provides a convenient way to express very large viscosity measurements without resorting to exponential notation.
History & Origin
The terapoise emerged from the need to quantify extremely high viscosities in various scientific fields, particularly in polymer science and material engineering. It was developed in the mid-20th century as researchers began to explore the properties of synthetic fluids that exhibited significantly higher viscosity than previously known materials. The terapoise is part of the centimeter-gram-second (CGS) system, with the poise named after the French scientist Jean Louis Marie Poiseuille, who made substantial contributions to fluid dynamics.
Etymology: The term 'terapoise' derives from the prefix 'tera-', indicating a factor of 10^12, combined with 'poise', named after the physicist Jean Louis Marie Poiseuille, who studied laminar flow.
Current Use
The terapoise is predominantly used in scientific research and industrial applications where extremely high viscosity fluids are analyzed. Industries such as petroleum, polymers, and food processing may utilize this unit to assess the flow characteristics of materials. However, its application is mainly restricted to laboratories as standard industrial measurements typically do not reach such high viscosity levels.
💡 Fun Facts
- •The terapoise is rarely encountered in everyday applications, as most fluids have much lower viscosities.
- •It is estimated that only specialized laboratories use the terapoise for viscosity measurements beyond typical industrial levels.
- •The poise was originally defined by measuring the resistance of a fluid to flow through a tube, leading to the development of more complex units like the terapoise.
