The Pascal second per square meter (Pa·s/m²) is a derived unit of dynamic viscosity in the International System of Units (SI). It quantifies a fluid's internal resistance to flow, providing essential insights into fluid dynamics. This unit is particularly relevant in various scientific and engineering applications, including chemical engineering, material science, and physics.
Dynamic viscosity measures a fluid's resistance to shear or flow. The unit Pa·s/m² indicates how much force is required to move a fluid layer over another layer. A higher value signifies a thicker fluid, while a lower value indicates a more fluid-like substance.
The unit is standardized by the International System of Units (SI) and is derived from the Pascal (Pa), which measures pressure, and the second (s), which measures time. This standardization ensures consistency in measurements across scientific disciplines.
The concept of viscosity dates back to the early studies of fluid mechanics in the 17th century. The term "viscosity" itself was introduced by Sir Isaac Newton, who formulated the relationship between shear stress and shear rate. Over time, the unit has evolved, with the Pascal second becoming the standard in modern scientific applications.
To illustrate the use of Pa·s/m², consider a fluid with a dynamic viscosity of 5 Pa·s. If you need to calculate the force required to move a fluid layer of 1 m² at a shear rate of 1 s⁻¹, the calculation would be:
[ Force = Viscosity \times Area \times Shear Rate ]
[ Force = 5 , \text{Pa·s} \times 1 , \text{m²} \times 1 , \text{s}^{-1} = 5 , \text{N} ]
The Pa·s/m² unit is widely used in industries such as food processing, pharmaceuticals, and petrochemicals, where understanding fluid behavior is crucial for process design and quality control.
To use the dynamic viscosity tool effectively:
What is dynamic viscosity? Dynamic viscosity is a measure of a fluid's resistance to flow and shear. It quantifies how easily a fluid can move under applied force.
How do I convert Pa·s/m² to other viscosity units? You can use our dynamic viscosity converter tool to easily convert Pa·s/m² to other units such as centipoise (cP) or poise (P).
What industries commonly use the Pa·s/m² unit? Industries such as food processing, pharmaceuticals, and petrochemicals frequently utilize the Pa·s/m² unit for analyzing fluid behavior.

Poise (symbol: P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system. It quantifies a fluid's internal resistance to flow, which is essential in various scientific and engineering applications. One poise is defined as the viscosity of a fluid that requires a force of one dyne per square centimeter to move a layer of fluid with a velocity of one centimeter per second.
The poise is standardized in the CGS system, where it is commonly used in fields such as physics, engineering, and material science. For practical applications, the poise is often converted to the more commonly used SI unit, the pascal-second (Pa·s), where 1 P equals 0.1 Pa·s. This conversion is vital for ensuring consistency in measurements across different scientific disciplines.
The term "poise" is named after the French scientist Jean Louis Marie Poiseuille, who made significant contributions to fluid dynamics in the 19th century. His work laid the foundation for understanding how fluids behave under various conditions, leading to the establishment of viscosity as a critical property in fluid mechanics.
To illustrate how to use the poise unit, consider a fluid with a viscosity of 5 P. To convert this to pascal-seconds, you would multiply by 0.1: [ 5 , \text{P} \times 0.1 = 0.5 , \text{Pa·s} ] This conversion is essential for engineers and scientists who require precise measurements in their calculations.
The poise unit is particularly useful in industries such as food processing, pharmaceuticals, and petrochemicals, where understanding the flow characteristics of fluids is crucial. For example, the viscosity of oils, syrups, and other liquids can significantly affect processing and product quality.
