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.
MillistokesmSt
Target UnitThe millistoke (mSt) is a measurement of kinematic viscosity, which describes a fluid's internal resistance to flow. It is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of 1 centipoise and a density of 1 g/cm³. The stoke, the base unit, is derived from the CGS system and is equivalent to 10^−4 m²/s. Thus, 1 millistoke equals 10^−6 m²/s. This measurement is particularly useful in characterizing fluid behavior in various scientific and industrial applications, allowing for better understanding of fluid dynamics.
Current Use
Millistokes are widely used in industries that require precise knowledge of fluid behavior, such as petrochemicals, food processing, and pharmaceuticals. Engineers and scientists often measure the viscosity of fluids to ensure proper mixing, pumping, and processing conditions. In laboratories, millistokes are essential for characterizing new materials and conducting research in fluid dynamics.
Fun Fact
The stoke is named after Sir George Stokes, who is also known for his work on fluid dynamics.

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.

viscosity • Non-SI
Definition
The millistoke (mSt) is a measurement of kinematic viscosity, which describes a fluid's internal resistance to flow. It is defined as the kinematic viscosity of a fluid that has a dynamic viscosity of 1 centipoise and a density of 1 g/cm³. The stoke, the base unit, is derived from the CGS system and is equivalent to 10^−4 m²/s. Thus, 1 millistoke equals 10^−6 m²/s. This measurement is particularly useful in characterizing fluid behavior in various scientific and industrial applications, allowing for better understanding of fluid dynamics.
History & Origin
The concept of kinematic viscosity dates back to the 19th century when scientists began quantifying fluid behavior. The stoke was named after Sir George Gabriel Stokes, who described the motion of viscous fluids in 1851. The millistoke was derived to provide a more practical subunit for measuring low viscosities, particularly in laboratory settings and industrial applications, where precise measurements are essential.
Etymology: The term 'millistoke' combines the prefix 'milli-' from Latin, meaning one-thousandth, with 'stoke,' named after Sir George Stokes.
Current Use
Millistokes are widely used in industries that require precise knowledge of fluid behavior, such as petrochemicals, food processing, and pharmaceuticals. Engineers and scientists often measure the viscosity of fluids to ensure proper mixing, pumping, and processing conditions. In laboratories, millistokes are essential for characterizing new materials and conducting research in fluid dynamics.
💡 Fun Facts
- •The stoke is named after Sir George Stokes, who is also known for his work on fluid dynamics.
- •Millistokes allow for better representation of low viscosity fluids, crucial in many industrial processes.
- •Kinematic viscosity is temperature-dependent, meaning the same fluid can have different mSt values at different temperatures.
