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?
To convert centipoise (cP) to Stokes (St), divide the cP value by the fluid's density in grams per cubic centimeter (g/cm³).
3. Why is understanding viscosity important?
Understanding viscosity is crucial for various applications, including fluid transport, mixing processes, and quality control in industries like food, pharmaceuticals, and petroleum.
4. Can I use the Stokes converter for any fluid?
Yes, the Stokes converter can be used for any fluid, but ensure you have accurate viscosity and density values for reliable conversions.

Millipascal second (mPa·s) is a unit of dynamic viscosity, which measures a fluid's resistance to flow. It is a derived unit in the International System of Units (SI), where one millipascal second is equal to one-thousandth of a pascal second (Pa·s). Viscosity is a critical property in various industries, including food, pharmaceuticals, and manufacturing, as it affects how liquids behave under different conditions.
The millipascal second is standardized under the SI system, which provides a consistent framework for measurement across scientific and industrial applications. This standardization ensures that viscosity measurements can be universally understood and applied, facilitating better communication and collaboration in research and industry.
The concept of viscosity dates back to the early studies of fluid dynamics in the 17th century. The term "viscosity" itself was introduced in the 19th century. Over time, various units have been used to measure viscosity, but the pascal second and its subunits, including millipascal second, have become the preferred standards due to their alignment with the SI system.
To illustrate the use of millipascal second, consider a fluid with a viscosity of 500 mPa·s. This means that the fluid exhibits a moderate resistance to flow, which is typical for many syrups and oils. If you were to compare this to water, which has a viscosity of approximately 1 mPa·s, you can see how much thicker the syrup is.
Millipascal second is commonly used in industries that require precise control of fluid properties. For example, in the food industry, understanding the viscosity of sauces and dressings is crucial for ensuring the right texture and mouthfeel. In pharmaceuticals, the viscosity of liquid medications can affect their absorption and efficacy.
