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.
NanostokesnSt
Target UnitThe nanostoke (symbol: nSt) is a unit of kinematic viscosity, which quantifies the internal resistance of a fluid to flow under the influence of gravity. One nanostoke is equivalent to 10^-9 stokes, where one stoke is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of 1 centipoise and a density of 1 g/cm³. This unit is useful for describing the properties of extremely low-viscosity fluids, particularly in the fields of microfluidics and nanotechnology.
Current Use
Nanostokes are widely used in fields such as microfluidics, where precise viscosity measurements are crucial for the design and operation of devices that manipulate fluids at the microscale. They are also relevant in biomedical applications, including the analysis of blood viscosity and the behavior of bodily fluids. Industries such as pharmaceuticals and materials science utilize nanostokes to characterize the flow properties of various substances.
Fun Fact
The term 'stokes' is often used in fluid dynamics and is a tribute to Sir George Gabriel Stokes, who made significant contributions to the field.

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 is useful for describing the properties of extremely low-viscosity fluids, particularly in the fields of microfluidics and nanotechnology.
History & Origin
The concept of viscosity dates back to the early studies of fluid mechanics, but the specific term 'stokes' was introduced in the late 19th century by the British scientist Sir George Gabriel Stokes. The nanostokes, being a subunit of stokes, was developed in the 20th century as the need for more precise measurements of fluid dynamics in small-scale applications emerged, particularly in the context of scientific research and industrial processes.
Etymology: The term 'nanostokes' combines the prefix 'nano-', meaning one billionth (10^-9), with 'stokes', named after Sir George Gabriel Stokes.
Current Use
Nanostokes are widely used in fields such as microfluidics, where precise viscosity measurements are crucial for the design and operation of devices that manipulate fluids at the microscale.

💡 Fun Facts
- •The term 'stokes' is often used in fluid dynamics and is a tribute to Sir George Gabriel Stokes, who made significant contributions to the field.
- •Nanostokes are particularly important in the emerging field of nanotechnology, where fluid behavior at the nanoscale can differ significantly from macro-scale behavior.
- •The viscosity of fluids can change dramatically with temperature, making precise measurements crucial in many scientific applications.
