Stokes (St) is a unit of measurement for kinematic viscosity, which quantifies a fluid's resistance to flow under the influence of gravity. It is defined as the ratio of dynamic viscosity to fluid density. The higher the Stokes value, the thicker the fluid, indicating a greater resistance to flow.
Stokes is standardized in the International System of Units (SI) and is commonly used in various scientific and engineering applications. One Stokes is equivalent to one square centimeter per second (cm²/s). This standardization allows for consistent measurement and comparison across different fluids and applications.
The term "Stokes" is named after the Irish mathematician and physicist George Gabriel Stokes, who made significant contributions to fluid dynamics in the 19th century. The unit has evolved over time, becoming a standard in various industries, including engineering, chemistry, and physics, for assessing fluid behavior.
To convert dynamic viscosity from centipoise (cP) to Stokes, you can use the following formula:
[ \text{St} = \frac{\text{cP}}{\text{Density (g/cm}^3\text{)}} ]
For example, if a fluid has a dynamic viscosity of 10 cP and a density of 0.8 g/cm³:
[ \text{St} = \frac{10 \text{ cP}}{0.8 \text{ g/cm}^3} = 12.5 \text{ St} ]
Stokes is widely used in industries such as petroleum, food processing, and pharmaceuticals, where understanding fluid viscosity is crucial for processes like mixing, pumping, and quality control. By converting viscosity measurements into Stokes, engineers and scientists can make informed decisions regarding fluid behavior in various applications.
To use the Stokes dynamic viscosity converter tool, follow these simple steps:
1. What is Stokes in viscosity measurement?
Stokes is a unit of kinematic viscosity that measures a fluid's resistance to flow, defined as the ratio of dynamic viscosity to fluid density.
2. How do I convert centipoise to Stokes?

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:
