Unit Explanations
StokesSt
Source UnitThe stokes (symbol: St) is a unit of measurement for kinematic viscosity, defined as the kinematic viscosity of a fluid in which a sphere of unit radius falls under the influence of gravity at a velocity of one centimeter per second. One stokes is equivalent to one square centimeter per second (cm²/s). This unit is named after the Irish scientist George Gabriel Stokes, who made significant contributions to fluid dynamics, particularly in understanding the motion of viscous fluids.
Current Use
Stokes are primarily used in fields such as engineering, physics, and material science to quantify the kinematic viscosity of various fluids, including oils, water, and other liquids. While the use of stokes has diminished due to the transition to SI units, it is still prevalent in specialized literature and applications involving fluid dynamics.
Fun Fact
The stokes is often used in laboratory settings to test the viscosity of various liquids under controlled conditions.
CentistokescSt
Target UnitCentistokes (cSt) is a unit of kinematic viscosity in the metric system, defined as the viscosity of a fluid under the influence of gravity. Specifically, one centistoke is equivalent to 1 mm²/s (square millimeter per second). It is commonly used in various fields such as engineering, fluid mechanics, and material science to describe the flow characteristics of liquids. The kinematic viscosity reflects how a fluid flows under its own gravity and is essential for determining the behavior of fluids in motion.
Current Use
Centistokes are extensively used in industries such as petrochemicals, food, pharmaceuticals, and cosmetics to measure the flow properties of liquids. For example, they are crucial in formulating paints, inks, and lubricants, where understanding viscosity is essential for product performance. The unit's relevance extends across the globe, as many countries have adopted the metric system, leading to the widespread use of centistokes in technical specifications and safety standards.
Fun Fact
The centistoke is equivalent to 1 mm²/s, making it easier to convert between metric viscosity measurements.

Definition
The stokes (symbol: St) is a unit of measurement for kinematic viscosity, defined as the kinematic viscosity of a fluid in which a sphere of unit radius falls under the influence of gravity at a velocity of one centimeter per second. One stokes is equivalent to one square centimeter per second (cm²/s). This unit is named after the Irish scientist George Gabriel Stokes, who made significant contributions to fluid dynamics, particularly in understanding the motion of viscous fluids.
History & Origin
The stokes unit was introduced in the mid-19th century as part of the centimeter-gram-second (CGS) system of units, which was widely used in scientific contexts before the adoption of the International System of Units (SI). The concept of kinematic viscosity was developed to describe the intrinsic resistance of fluids to flow, a fundamental property in fluid dynamics and engineering.
Etymology: The unit is named after George Gabriel Stokes, a prominent 19th-century physicist and mathematician known for his work in fluid mechanics and optics.
Current Use
Stokes are primarily used in fields such as engineering, physics, and material science to quantify the kinematic viscosity of various fluids, including oils, water, and other liquids.

Centistokes
viscosity • Non-SI
Definition
Centistokes (cSt) is a unit of kinematic viscosity in the metric system, defined as the viscosity of a fluid under the influence of gravity. Specifically, one centistoke is equivalent to 1 mm²/s (square millimeter per second). It is commonly used in various fields such as engineering, fluid mechanics, and material science to describe the flow characteristics of liquids. The kinematic viscosity reflects how a fluid flows under its own gravity and is essential for determining the behavior of fluids in motion.
History & Origin
The term 'centistoke' originates from the stoke, named after the British engineer Sir George Stokes, who contributed significantly to fluid dynamics in the 19th century. The stoke itself is defined in terms of kinematic viscosity in the CGS (centimeter-gram-second) system, where 1 stoke equals 100 mm²/s. The centistoke, as a subdivision of the stoke, was introduced to provide a more manageable unit for measuring low viscosities, especially in industrial applications where fluids often exhibit such properties.
Etymology: The word 'centistoke' is derived from 'centi-', a metric prefix meaning one-hundredth, combined with 'stoke', named after Sir George Stokes.
Current Use
Centistokes are extensively used in industries such as petrochemicals, food, pharmaceuticals, and cosmetics to measure the flow properties of liquids. For example, they are crucial in formulating paints, inks, and lubricants, where understanding viscosity is essential for product performance. The unit's relevance extends across the globe, as many countries have adopted the metric system, leading to the widespread use of centistokes in technical specifications and safety standards.
💡 Fun Facts
- •The centistoke is equivalent to 1 mm²/s, making it easier to convert between metric viscosity measurements.
- •Water at 20°C has a viscosity of approximately 1 cSt, serving as a standard reference for many fluid viscosity measurements.
- •The term 'stokes' is sometimes humorously referenced in fluid dynamics discussions as fluids that 'stoke' the fire of industry.
