Tips & Best Practices
-
Use this tool to clearly translate between large kinematic viscosity units suited for different measurement systems
-
Double-check unit relevance according to the specific viscosity magnitude of your fluid
-
Ensure conversions are handled carefully in engineering calculations to reduce rounding errors
-
Understand the context of high-viscosity fluids when interpreting results in square foot per second
-
Refer to both metric and Imperial unit standards when preparing technical documentation
Limitations
-
Both kilostokes and square foot/second are large units intended for very high viscosity values only
-
Care is required during conversion to maintain precision for engineering uses
-
The usefulness of these units depends on the viscosity range relevant to the application
-
Not suitable for low viscosity measurements where smaller units are preferred
Frequently Asked Questions
-
What is a kilostoke used for?
-
A kilostoke measures very high kinematic viscosity and is used for heavy oils, bitumen, polymer melts, and very slow-moving fluids like some lava.
-
Why convert kilostokes to square foot per second?
-
Converting to square foot per second provides the viscosity in Imperial units common in US engineering, useful for calculations and comparisons with international standards.
-
Can I use this converter for low viscosity fluids?
-
No, kilostokes and square foot per second are both large units intended for very viscous fluids; smaller units are more appropriate for low viscosity measurements.
Key Terminology
-
Kilostoke (kSt)
-
A unit of kinematic viscosity equal to 1,000 stokes, where 1 stoke = 1 cm²/s, used for very high viscosity fluids.
-
Square foot/second (ft²/s)
-
An Imperial unit measuring kinematic viscosity representing the fluid's resistance to flow, used in US customary engineering.
-
Kinematic Viscosity
-
A measure of a fluid's resistance to flow under gravity calculated as the ratio of dynamic viscosity to density.
