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.
MillipoisemP
Target UnitThe millipoise (mP) is a derived unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as one-thousandth of a poise (P), where one poise is the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when flowing with a velocity gradient of one reciprocal second. The millipoise is predominantly used in various scientific and industrial applications to quantify the resistance of fluids to flow under specific conditions. It serves as a practical measurement for low-viscosity liquids.
Current Use
Today, the millipoise is widely used in industries such as food processing, cosmetics, pharmaceuticals, and petrochemicals to determine the viscosity of various liquids. It is essential for quality control and formulation processes, allowing manufacturers to ensure that products maintain the desired texture and flow characteristics. The millipoise is particularly useful for testing low-viscosity fluids, where precise measurements are critical for product consistency and performance.
Fun Fact
The millipoise is often used in laboratories to measure the viscosity of liquids in experiments and formulations.

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
- •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.

The millipoise (mP) is a derived unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units.

It serves as a practical measurement for low-viscosity liquids.
History & Origin
The millipoise is part of the CGS system of measurement that was widely used in the 19th century. The poise was named after the French physicist Jean Léonard Marie Poiseuille, who studied fluid dynamics and the flow of liquids. The millipoise was subsequently introduced as a convenient subunit to measure lower viscosity values, making it easier for scientists and engineers to work with a wider range of fluids, particularly in laboratory settings.
Etymology: The term 'millipoise' combines 'milli-', a prefix meaning one-thousandth, with 'poise', which honors the contributions of Jean Léonard Marie Poiseuille.

💡 Fun Facts
- •The millipoise is often used in laboratories to measure the viscosity of liquids in experiments and formulations.
- •Many common household products, such as shampoos and lotions, are formulated with specific viscosities measured in millipoise.
- •The viscosity of a fluid can change significantly with temperature, making it an important factor in product formulation.
