What Is This Tool?
This unit converter transforms dynamic viscosity values expressed in pound/foot/second to pound/foot/hour [lb/(ft*h)]. It helps engineers and technicians working with imperial units align viscosity data across different time bases for fluid flow, shear stress, and mechanical applications.
How to Use This Tool?
-
Enter the viscosity value in pound/foot/second.
-
Select the target unit pound/foot/hour [lb/(ft*h)].
-
Click the convert button to see the corresponding value in pound/foot/hour.
-
Use the result for engineering calculations or documentation that requires hour-based time units.
Key Features
-
Converts dynamic viscosity measures between pound/foot/second and pound/foot/hour units.
-
Supports engineering workflows using US customary and imperial measurement systems.
-
Provides accurate scaling based on the fixed conversion factor 1 lb/(ft·s) = 3599.9999999974 lb/(ft·h).
Examples
-
Convert 2 pound/foot/second: 2 × 3599.9999999974 = 7199.999999995 pound/foot/hour.
-
Convert 0.5 pound/foot/second: 0.5 × 3599.9999999974 = 1799.9999999987 pound/foot/hour.
Common Use Cases
-
Engineering fluid flow and shear stress calculations using imperial units.
-
Specifying lubricant or oil viscosity in US customary datasheets.
-
Reporting viscosity for fuels and industrial fluids in hour-based unit contexts.
Tips & Best Practices
-
Ensure measurement conditions such as temperature and pressure are consistent before conversion.
-
Maintain precision due to the large conversion factor near 3600 when converting.
-
Be aware of regional and legacy documentation requirements for hour-based viscosity units.
Limitations
-
High conversion factor necessitates careful handling to keep accuracy for sensitive calculations.
-
Tool is designed for imperial units; further conversion to SI units like pascal-seconds may be needed.
-
Viscosity measurements must be consistent in physical conditions to avoid errors unrelated to conversion.
Frequently Asked Questions
-
Why convert from pound/foot/second to pound/foot/hour?
-
This conversion aligns viscosity data with time units used in specific engineering standards, legacy datasheets, or regional documents that use hour-based time measurement.
-
In which industries is this conversion most commonly used?
-
It is frequently applied in petroleum refining, lubricant manufacturing, hydraulic system design, chemical processing, and mechanical engineering using imperial units.
-
Does the tool handle viscosity unit conversions to SI units like pascal-seconds?
-
No, this tool specifically converts between imperial dynamic viscosity units; conversion to SI units requires separate calculation.
Key Terminology
-
Pound/foot/second
-
An imperial unit of dynamic viscosity, measuring force times time per area, used in US customary fluid flow and shear stress calculations.
-
Pound/foot/hour [lb/(ft*h)]
-
An imperial engineering unit representing dynamic viscosity with time measured in hours, applied in legacy or regional technical contexts.
-
Dynamic Viscosity
-
A measure of a fluid's internal resistance to shear flow, relating shear stress to velocity gradient.
