What Is This Tool?
This tool converts dynamic viscosity measurements from decipoise (dP), a CGS unit, to pound per foot per hour (lb/(ft*h)), an imperial engineering unit. It facilitates the translation of viscosity values for industrial, laboratory, and engineering purposes, enabling compatibility across different measurement systems.

Examples
-
Convert 2 dP to lb/(ft*h): 2 × 24.190883105 = 48.38176621 lb/(ft*h).
-
Convert 0.5 dP to lb/(ft*h): 0.5 × 24.190883105 = 12.09544155 lb/(ft*h).
Common Use Cases
-
Specifying lubricating oil viscosities in engineering or industrial data sheets using imperial units.
-
Performing viscous flow calculations for piping, bearings, or rotating machinery in US customary units.
-
Reporting viscosity values for fuels, process fluids, and industrial liquids in legacy technical documents.
-
Converting laboratory viscosity measurements for compatibility with imperial engineering standards.
Tips & Best Practices
-
Ensure temperature and pressure conditions match when comparing viscosity values, as they can affect results.
-
Double-check the unit selections before conversion to avoid errors.
-
Use the conversion factor of 24.190883105 for accurate unit translation.
-
Understand that the pound/foot/hour unit uses an hour-based time scale, which may need adjustment when interacting with SI-second-based processes.
Limitations
-
The conversion assumes standard unit definitions without accounting for temperature or pressure effects on viscosity.
-
Dynamic viscosity varies with temperature, so conversions should consider matching measurement conditions.
-
The use of an hour-based time unit in pound/foot/hour may require converting to seconds for some engineering calculations.
Frequently Asked Questions
-
What does decipoise measure?
-
Decipoise (dP) is a CGS unit of dynamic viscosity, representing a fluid's resistance to flow and equal to one tenth of a poise.
-
Why use pound/foot/hour for viscosity?
-
Pound/foot/hour is an imperial engineering unit expressing dynamic viscosity, commonly used in US customary measurements and legacy technical documents.
-
How do I convert decipoise to pound/foot/hour?
-
Multiply the viscosity value in decipoise by 24.190883105 to get the equivalent viscosity in pound/foot/hour.
-
Are temperature effects accounted for in this conversion?
-
No, the conversion assumes standard conditions and does not include temperature or pressure corrections.
Key Terminology
-
Decipoise (dP)
-
A CGS unit of dynamic viscosity equal to one tenth of a poise, measuring a fluid's resistance to shear flow.
-
Pound/foot/hour [lb/(ft*h)]
-
An imperial engineering unit expressing dynamic viscosity, relating shear stress to velocity gradient based on force and time per unit area.
-
Dynamic Viscosity
-
A physical property indicating a fluid's internal resistance to flow or shear under applied force.
