What Is This Tool?
This converter transforms dynamic viscosity values from pound/foot/hour to pound/foot/second, facilitating the interpretation of fluid resistance data within imperial measurement systems commonly used in engineering and industrial settings.
How to Use This Tool?
-
Enter the viscosity value in pound/foot/hour [lb/(ft*h)] into the input field
-
Select the target unit, which is pound/foot/second [lb/(ft*s)]
-
Click the convert button to get the corresponding value in pound/foot/second
-
Use the result for engineering calculations or documentation requiring second-based units
Key Features
-
Converts dynamic viscosity expressed in pound/foot/hour to pound/foot/second
-
Supports engineering and industrial unit systems with imperial standard units
-
Provides easy input and immediate conversion results based on accepted formulas
-
Facilitates integration of legacy data with modern per-second time unit requirements
Examples
-
Convert 5 lb/(ft*h): 5 × 0.0002777778 = 0.001388889 lb/(ft*s)
-
Convert 10 lb/(ft*h): 10 × 0.0002777778 = 0.002777778 lb/(ft*s)
Common Use Cases
-
Specifying lubricant or oil viscosity in US-customary engineering datasheets
-
Performing viscous flow analyses in imperial units for piping, bearings, or rotating equipment
-
Documenting viscosity values for fuels and industrial fluids in regional technical materials
-
Engineering fluid flow or shear stress calculations using imperial units
-
Laboratory testing where instrumentation uses imperial-based dynamic viscosity measurements
Tips & Best Practices
-
Confirm the source data uses the correct unit before converting to prevent errors
-
Verify the consistency of time units when integrating converted values into calculations
-
Use this tool to reliably handle legacy data that employs hour-based viscosity measurements
-
Double-check conversion results when applying viscosity values to equipment design or process control
-
Understand that proper unit conversions are vital to ensure valid engineering outcomes
Limitations
-
Hour and second units differ by a factor of 3600; incorrect conversions cause major result errors
-
Users must ensure unit consistency across all data to maintain calculation accuracy
-
This tool assumes input values conform to the pound/foot/hour measurement context for dynamic viscosity
-
The converter does not accommodate other dynamic viscosity units beyond pound/foot/hour and pound/foot/second
Frequently Asked Questions
-
Why convert from pound/foot/hour to pound/foot/second?
-
Converting to pound/foot/second allows compatibility with engineering calculations and instrumentation that require time units based on seconds rather than hours.
-
What industries commonly use this conversion?
-
Mechanical engineering, oil and lubricant formulation, fluid dynamics in piping and bearings, and petroleum processing often rely on this conversion in US customary systems.
-
What happens if I misapply the conversion factor?
-
Since the difference between hour and second is significant, improper conversion can lead to large errors affecting equipment design and process control reliability.
