Pascal Second [Pa·s]

Pascal second (Pa·s) is the SI unit of dynamic viscosity, which measures a fluid’s resistance to flow under an applied force. One pascal second represents a shear stress of one pascal (1 Pa) causing a fluid layer to move with a velocity gradient of one meter per second per meter of thickness. In simpler terms, it quantifies how “thick” or “sticky” a fluid is: higher Pa·s values indicate more viscous fluids, while lower values indicate thinner, easily flowing fluids. For example, water at room temperature has a viscosity of about 0.001 Pa·s, whereas honey can have a viscosity exceeding 10 Pa·s. Pascal second is widely used in fluid mechanics, chemical engineering, lubrication studies, and materials science to design pumps, pipelines, and fluid-based processes. Converting to other viscosity units is straightforward: 1 Pa·s = 10 poise (P) = 1,000 centipoise (cP). Understanding viscosity in Pa·s allows engineers and scientists to predict flow behavior, optimize fluid transport, and ensure accurate performance in industrial, laboratory, and natural systems.

Gram per Centimeter per Second [g/(cm·s)]

Gram per centimeter per second, symbolized as g/(cm·s), is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system. Dynamic viscosity measures a fluid’s internal resistance to flow when a force is applied. In this unit, it represents the force, in grams, required to move a layer of fluid one centimeter thick over an area of one square centimeter at a velocity of one centimeter per second. High values of g/(cm·s) indicate thicker, more viscous fluids, like honey or heavy oils, while lower values correspond to thinner fluids, such as water or light oils. This unit is commonly used in laboratory measurements, fluid mechanics studies, and chemical engineering processes, particularly when precise small-scale viscosity measurements are needed. Although the SI unit of dynamic viscosity is the Pascal-second (Pa·s), g/(cm·s) remains relevant in CGS-based calculations and historical data. Understanding viscosity in g/(cm·s) helps scientists and engineers design equipment, predict fluid behavior, and ensure efficient operation in pipelines, lubricants, and industrial fluid systems.
