Tips & Best Practices
-
Ensure units are correctly selected before converting to avoid errors
-
Use this converter to translate legacy engineering data into modern scientific units
-
Verify the temperature and pressure conditions as they influence viscosity beyond unit conversion
-
Refer to example values to confirm conversion accuracy
Limitations
-
Conversion accuracy depends on correct handling of the hour-to-second time unit difference
-
Assumes fluid characteristics under standard temperature and pressure
-
Pound/foot/hour is less common in modern SI-based laboratory contexts, limiting direct use
-
Changes in fluid temperature or pressure affect viscosity independently of the units used
Frequently Asked Questions
-
What does pound/foot/hour measure in viscosity?
-
Pound/foot/hour is an imperial engineering unit expressing a fluid's resistance to shear, relating shear stress to velocity gradient.
-
Why convert pound/foot/hour to millinewton second/sq. meter?
-
Converting to millinewton second per square meter translates viscosity values into SI units widely used in scientific analysis and quality control.
-
Are temperature and pressure considered in this unit conversion?
-
This conversion assumes standard temperature and pressure; changes in these conditions influence viscosity beyond unit changes.
Key Terminology
-
Pound/foot/hour [lb/(ft*h)]
-
