Tips & Best Practices
-
Confirm the correct units are selected before converting to avoid errors.
-
Use this conversion when compatibility with legacy or regional datasets is necessary.
-
Keep in mind the time unit difference (hours vs seconds) when applying results to sensitive processes.
-
Cross-check converted values when dealing with highly precise engineering calculations.
-
Refer to example conversions to understand scale and magnitude.
Limitations
-
Time units expressed in hours may impact accuracy in second-based process calculations.
-
Rounding or consistency issues may arise due to differences between SI and imperial unit definitions.
-
Large conversion factors require careful application in sensitive engineering scenarios.
Frequently Asked Questions
-
Why convert pascal second to pound/foot/hour?
-
Converting helps engineers and technicians use viscosity data across systems that utilize SI or imperial units, supporting legacy systems and regional reporting needs.
-
What industries use pound/foot/hour for dynamic viscosity?
-
Mechanical engineering, petroleum refining, chemical processing, and lubricant manufacturing commonly employ pound/foot/hour in their measurements.

Yes, the use of hours in time units and differences between SI and imperial standards can introduce rounding or unit consistency challenges.
Key Terminology
-
Pascal second [Pa*s]
-
SI derived unit of dynamic viscosity representing resistance to shear flow, defined as one pascal of shear stress per unit shear rate.
-
Pound/foot/hour [lb/(ft*h)]
-
Imperial engineering unit expressing dynamic viscosity as force-time per area over hours, used in customary unit systems.
-
Dynamic viscosity
-
A measure of a fluid's internal resistance to flow or deformation under shear stress.
