What Is This Tool?
This converter allows users to transform dynamic viscosity measurements expressed in pound/foot/hour, an imperial engineering unit, into kilogram-force second per square meter, a non-SI metric force unit used in viscosity contexts. It facilitates compatibility between legacy imperial data and metric unit systems.

-
Converting legacy fluid property data to SI-compatible units for rheological analysis
-
Reporting viscosities for hydraulic fluids in systems designed with non-SI force units
Tips & Best Practices
-
Double-check the time unit since pound/foot/hour is hour-based while the metric may involve seconds
-
Consider additional conversion to pascal-second if standard SI units are needed
-
Ensure numerical accuracy due to the small conversion factor to avoid precision loss
-
Use consistent unit systems within the engineering or scientific context to avoid errors
Limitations
-
The conversion factor is small, which can affect numerical precision if not handled properly
-
Pound/foot/hour uses an hour-based time scale that requires careful comparison with second-based units
-
Kilogram-force second/square meter is a non-SI unit and often needs further conversion for SI analyses
Frequently Asked Questions
-
What does pound/foot/hour measure in fluid mechanics?
-
It measures dynamic viscosity, representing a fluid's resistance to shear using imperial engineering units based on force and time per area.
-
Why convert to kilogram-force second per square meter?
-
This unit helps report or interpret viscosity values in systems or documents that use kilogram-force units, offering compatibility with non-SI engineering data.
-
Can I use kilogram-force second/square meter directly in SI-based calculations?
-
Since it is a non-SI unit, it often requires further conversion to pascal-second for proper SI-based fluid dynamic analyses.
