What Is This Tool?
This online unit converter allows you to change values of kinematic viscosity from femtostokes (fSt), a CGS-based unit for very small viscosities, into square foot per hour (ft²/h), an imperial unit commonly used in engineering.
How to Use This Tool?
-
Enter the value in femtostokes (fSt) you wish to convert.
-
Select square foot per hour (ft²/h) as the output unit.
-
Press convert to see the equivalent viscosity value in ft²/h.
Key Features
-
Converts kinematic viscosity from femtostokes to square foot/hour accurately.
-
Supports extremely small viscosity values relevant for nanoscale and molecular simulations.
-
Provides easy access to both CGS and imperial unit conversion in one tool.
Examples
-
10 fSt converts to 3.8750077500155e-14 ft²/h
-
100 fSt converts to 3.8750077500155e-13 ft²/h
Common Use Cases
-
Converting very small viscosity measurements in nanoscale fluid simulations to imperial units.
-
Reporting low kinematic viscosity values for microfluidics or thin-film lubrication applications.
-
Comparing scientific or industrial data using CGS and imperial units in engineering systems.
Tips & Best Practices
-
Ensure clarity whether your data is in CGS or imperial units before converting.
-
Use this tool to facilitate understanding and comparison of viscosity values across different unit systems.
-
Be mindful that very small numerical values can be sensitive to rounding or precision.
Limitations
-
Conversion handles extremely small numeric values, so take care with rounding errors.
-
Intended for cases requiring precise small-scale viscosity values or unit standardization.
-
Not suitable for converting unrelated physical quantities or units outside kinematic viscosity.
Frequently Asked Questions
-
What does femtostokes measure?
-
Femtostokes is a CGS-derived unit measuring kinematic viscosity at extremely small scales, equal to 10⁻¹⁵ stokes or 1×10⁻¹⁹ m²/s.
-
Why convert femtostokes to square foot/hour?
-
Converting allows comparison of very small viscosity values reported in CGS units with imperial units commonly used in engineering fields.
-
Where is square foot/hour commonly used?
-
Square foot per hour is used in U.S.-customary engineering specifications for oils, fuels, lubricants, and hydraulic system analyses.
Key Terminology
-
Femtostokes [fSt]
