Unit Explanations
AttopoiseaP
Source UnitThe attopoise (symbol: aP) is a subunit of viscosity in the centimeter-gram-second (CGS) system, specifically representing dynamic viscosity. One attopoise is equal to 10^-18 poise, which can be understood as the viscosity of a fluid that offers a resistance of 1 dyne to a shear stress of 1 dyne per square centimeter. It is a very small measure, useful for quantifying extremely low viscosities found in certain nanofluids and other specialized applications in the field of fluid dynamics.
Current Use
Today, the attopoise is primarily used in scientific research, particularly in the fields of nanotechnology, molecular biology, and advanced fluid mechanics. It enables researchers to describe and quantify the viscosity of extremely thin films, nanofluids, and other complex fluids where traditional units would be inadequate. Industries such as pharmaceuticals, materials science, and nanotechnology utilize the attopoise in their research and applications.
Fun Fact
The attopoise is one of the smallest units of viscosity used in scientific measurements.
Pascal SecondPa·s
Target 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.

Definition
The attopoise (symbol: aP) is a subunit of viscosity in the centimeter-gram-second (CGS) system, specifically representing dynamic viscosity. One attopoise is equal to 10^-18 poise, which can be understood as the viscosity of a fluid that offers a resistance of 1 dyne to a shear stress of 1 dyne per square centimeter. It is a very small measure, useful for quantifying extremely low viscosities found in certain nanofluids and other specialized applications in the field of fluid dynamics.
History & Origin
The attopoise was introduced in the context of modern measurements of viscosity, particularly to describe extremely low viscosities encountered in advanced materials and nanotechnology. Its definition helps to quantify the behavior of fluids at the nanoscale, where conventional viscosity measures become impractical. The term reflects the trend toward using metric prefixes to create smaller units for precise scientific applications.
Etymology: The term 'attopoise' is derived from the prefix 'atto-' meaning 10^-18, combined with 'poise', which is named after the French physicist Jean Léonard Marie Poiseuille, who studied the flow of liquids.
Current Use
Today, the attopoise is primarily used in scientific research, particularly in the fields of nanotechnology, molecular biology, and advanced fluid mechanics. It enables researchers to describe and quantify the viscosity of extremely thin films, nanofluids, and other complex fluids where traditional units would be inadequate. Industries such as pharmaceuticals, materials science, and nanotechnology utilize the attopoise in their research and applications.
💡 Fun Facts
- •The attopoise is one of the smallest units of viscosity used in scientific measurements.
- •Fluid dynamics at the nanoscale can behave very differently than at larger scales, necessitating the use of such small units.
- •The introduction of metric prefixes has allowed for a more standardized approach to measuring extremely small quantities across various scientific disciplines.

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.

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.
