How to Convert Square Feet per Second to Stokes
To convert square feet per second to stokes, multiply the kinematic viscosity by the following conversion ratio: 929.0304 stokes/square foot per second.
Since one square foot per second is equal to 929.0304 stokes, you can use this simple formula to convert:
The kinematic viscosity in stokes is equal to the kinematic viscosity in square feet per second multiplied by 929.0304.
For example, here's how to convert 5 square feet per second to stokes using the formula above.
How Many Stokes Are in a Square Foot per Second?
There are 929.0304 stokes in a square foot per second, which is why we use this value in the formula above.
Our square foot per second to stokes calculator automatically converts your kinematic viscosity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Square Feet per Second and stokes are both units used to measure kinematic viscosity. Keep reading to learn more about each unit.
What Is a Square Foot per Second?
A square foot per second is a unit of kinematic viscosity equal to 0.092903 square meters per second (m²/s), the base unit for kinematic viscosity. Imperial kinematic viscosity unit (0.092903 m²/s). [1]
The square foot per second is classified as a US customary unit of kinematic viscosity. Square Feet per Second can be abbreviated as ft²/s; for example, 1 square foot per second can be written as 1 ft²/s.
When working with square feet per second (ft²/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, square feet per second (ft²/s) are widely used across standard kinematic viscosity applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Stokes?
A stokes is a unit of kinematic viscosity equal to 1/10,000 of a square meter per second (0.0001 m²/s). CGS kinematic viscosity unit equal to 1 cm²/s (0.0001 m²/s). [2]
The stokes is classified as a metric and SI-compatible unit of kinematic viscosity. Stokes can be abbreviated as St; for example, 1 stokes can be written as 1 St.
When working with stokes (St) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, stokes (St) are widely used across fine-tolerance laboratory, analytical, and micro-scale kinematic viscosity measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting kinematic viscosity between square feet per second (ft²/s) and stokes (St), keep full floating-point precision (1 ft²/s = 929.0304 St; 1 St = 0.0010764 ft²/s) during intermediate calculations and round only the final stokes figure to match your instrument tolerance.
