What Is This Tool?
This converter allows you to transform dynamic viscosity values expressed in micropoise, a cgs unit, into pound/foot/hour, an imperial engineering unit. It facilitates the translation of low-range viscosity measurements to the US-customary units often required in engineering and industrial applications.
How to Use This Tool?
-
Enter the dynamic viscosity value in micropoise (µP)
-
Select micropoise as the source unit if not preset
-
Choose pound/foot/hour as the target unit
-
Click convert to get the equivalent viscosity in lb/(ft*h)
-
Review the converted value for use in engineering or industrial calculations
Key Features
-
Converts micropoise (µP) to pound/foot/hour (lb/(ft*h)) dynamically
-
Supports low dynamic viscosity ranges relevant to gases and thin films
-
Uses standard conversion rates based on accepted definitions
-
Browser-based and easy to operate without installation
-
Facilitates comparison between cgs and imperial viscosity data
Examples
-
10 micropoise equals 0.002419088 pound/foot/hour
-
100 micropoise equals 0.02419088 pound/foot/hour
Common Use Cases
-
Reporting very low viscosities of gases or high-temperature fluids in cgs units
-
Calibrating and specifying low-range viscometers for microfluidics and lubrication studies
-
Converting historical rheological data to modern imperial units
-
Specifying lubricant or oil viscosity in legacy US engineering documents
-
Performing fluid flow calculations involving imperial units for piping and bearings
-
Reporting viscosity values for fuels and industrial fluids in hour-based time units
Tips & Best Practices
-
Ensure input viscosity values are accurate due to low magnitude of micropoise measurements
-
Cross-check conversions when integrating data using different time units
-
Be mindful of unit consistency in calculations involving both SI and imperial systems
-
Use this conversion mainly for engineering contexts where pound/foot/hour units are standard
Limitations
-
Micropoise values represent very low viscosities, so small errors can cause significant relative discrepancies
-
The hour time unit in pound/foot/hour may require care when mixing with second-based viscosity units
-
This tool does not cover other viscosity units beyond micropoise and pound/foot/hour
Frequently Asked Questions
-
What does micropoise measure?
-
Micropoise (µP) is a cgs unit that measures dynamic (shear) viscosity, indicating a fluid's resistance to shear.
-
When should I use pound/foot/hour for viscosity?
-
This unit is typically used in imperial engineering fields such as lubrication, pipe flow calculations, and processing fluids where hour-based time units are standard.
-
How do I avoid errors in converting viscosity units?
-
Pay close attention to unit consistency, especially regarding the time units, and ensure precise input values when converting between micropoise and pound/foot/hour.
Key Terminology
-
Micropoise [µP]
-
A cgs unit of dynamic viscosity equal to 1×10⁻⁶ poise or 1×10⁻⁷ pascal-second, representing low fluid resistance to shear.
-
Pound/foot/hour [lb/(ft*h)]
-
An imperial engineering unit of dynamic viscosity expressing fluid resistance to shear with hour-based time units, often used in US-customary contexts.
-
Dynamic viscosity
-
A measure of a fluid's internal resistance to shear stress during flow.
