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.
MicropoiseµP
Target UnitThe micropoise (µP) is a unit of dynamic viscosity, a measure of a fluid's resistance to flow. It is defined as one millionth of a poise, where one poise is equivalent to one gram per centimeter per second (g/cm·s). The micropoise is utilized primarily in specialized scientific and engineering applications, particularly when dealing with fluids of low viscosity. This unit allows for precise measurement of the flow characteristics of very thin liquids, such as certain oils, inks, and other industrial fluids, facilitating better control and quality within various processes.
Current Use
Today, the micropoise is extensively used in laboratories and industries that require precise viscosity measurements for low-viscosity fluids. It is particularly relevant in the fields of pharmaceuticals, food technology, and materials science, where understanding the flow properties of liquids is crucial for product formulation and quality control.
Fun Fact
The micropoise is so small that it is often used in combination with other units for practical measurements.

Pascal Second
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.

History & Origin
The micropoise was established in the 20th century as part of the metric system of measurement, which sought to provide a coherent and precise framework for scientific quantification. It was developed to address the need for measuring extremely low viscosities in various fluids, particularly in the fields of engineering and rheology.
Etymology: The term 'micropoise' is derived from the word 'poise,' named after the French physicist Jean Louis Marie Poiseuille, who made significant contributions to fluid dynamics. The prefix 'micro-' denotes a factor of one millionth, indicating the scale of the measurement.
Current Use
Today, the micropoise is extensively used in laboratories and industries that require precise viscosity measurements for low-viscosity fluids. It is particularly relevant in the fields of pharmaceuticals, food technology, and materials science, where understanding the flow properties of liquids is crucial for product formulation and quality control.
💡 Fun Facts
- •The micropoise is so small that it is often used in combination with other units for practical measurements.
- •Viscosity is temperature-dependent; as temperature increases, the viscosity of liquids typically decreases.
- •The micropoise is less commonly used than its larger counterpart, the poise, but it is essential for specific low-viscosity measurements.
