Unit Explanations
DecipoisedP
Source UnitThe decipoise (dP) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units, representing one-tenth of a poise (P). Viscosity measures a fluid's resistance to flow, and the poise is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when subjected to a shear rate of one reciprocal second. Therefore, one decipoise indicates that a fluid has a viscosity of ten centipoise (cP), and is often used in various scientific and engineering applications to quantify the flow properties of liquids.
Current Use
The decipoise is currently used in various industries including pharmaceuticals, food production, and petrochemicals, where precise viscosity measurements are crucial for quality control and product development. It is particularly useful for measuring the viscosity of non-Newtonian fluids and emulsions, which are common in these sectors. Laboratories and research institutions also utilize decipoise for experiments requiring accurate fluid dynamics assessments.
Fun Fact
The poise is rarely used in everyday applications, with the centipoise being more common, leading to the popularity of decipoise for intermediate 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.

viscosity • Non-SI
Definition
The decipoise (dP) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units, representing one-tenth of a poise (P). Viscosity measures a fluid's resistance to flow, and the poise is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when subjected to a shear rate of one reciprocal second. Therefore, one decipoise indicates that a fluid has a viscosity of ten centipoise (cP), and is often used in various scientific and engineering applications to quantify the flow properties of liquids.
History & Origin
The concept of viscosity dates back to the early studies of fluid dynamics in the 17th century, but the specific unit of the poise was named after French physicist Jean Léonard Marie Poiseuille, who contributed significantly to the understanding of fluid flow. The decipoise was later introduced as a subunit to provide finer measurements in the CGS system.
Etymology: The term 'decipoise' derives from the Latin prefix 'deci-', meaning one-tenth, combined with the name 'poise', which honors Poiseuille.
Current Use

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.
