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.
Square Foot Hourft²·h
Target UnitA square foot hour (ft²·h) is a unit of measurement that indicates the number of square feet of surface area that can be covered by a fluid in one hour, reflecting the fluid's viscosity relative to that area. Viscosity is a measure of a fluid's resistance to flow, and when expressed in square foot hours, it provides a practical context for evaluating the performance of coatings, paints, or liquids across a defined area over a specified time period. This unit is particularly useful in industries where material spread and application rates are critical.
Current Use
Today, the square foot hour is commonly utilized in industries such as paint manufacturing, adhesives, and surface coatings. It helps engineers and manufacturers calculate the spread rate of liquids and estimate drying times on various surfaces. This unit is essential for ensuring that products adhere to quality standards, facilitating effective application processes, and optimizing material usage.
Fun Fact
The square foot hour is particularly useful in optimizing the drying time of coatings, which can vary significantly based on environmental conditions.

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.

viscosity • Non-SI
Definition
A square foot hour (ft²·h) is a unit of measurement that indicates the number of square feet of surface area that can be covered by a fluid in one hour, reflecting the fluid's viscosity relative to that area. Viscosity is a measure of a fluid's resistance to flow, and when expressed in square foot hours, it provides a practical context for evaluating the performance of coatings, paints, or liquids across a defined area over a specified time period. This unit is particularly useful in industries where material spread and application rates are critical.
History & Origin
The square foot hour unit emerged from the need to quantify fluid dynamics in relation to surface applications. Historically, viscosity has been a fundamental property studied in fluids, but the specific combination of area and time in this unit gained traction in the mid-20th century. It reflects both the physical characteristics of the fluid and practical applications in industry, particularly in painting and coating processes where coverage and drying times are essential.
Etymology: The term 'square foot' derives from the basic unit of area in the imperial system, representing a square that is one foot on each side. The 'hour' component pertains to the standard unit of time, which is universally accepted in measuring duration.
Current Use
Today, the square foot hour is commonly utilized in industries such as paint manufacturing, adhesives, and surface coatings.
