What Is This Tool?
This converter transforms dynamic viscosity measurements from decipoise, a CGS unit, into pound/foot/second, an imperial unit commonly used in US customary systems. It helps convert fluid internal resistance to shear flow between different unit systems for various technical uses.
How to Use This Tool?
-
Enter the dynamic viscosity value in decipoise (dP) into the input field.
-
Select decipoise as the starting unit and pound/foot/second as the target unit.
-
Click convert to obtain the equivalent viscosity value in pound/foot/second.
-
Use the result to support engineering calculations or quality control involving fluid flow.
Key Features
-
Supports conversion between decipoise (dP) and pound/foot/second units.
-
Based on a defined conversion factor of 1 dP = 0.0067196898 pound/foot/second.
-
Facilitates viscosity unit translation for industrial, laboratory, and engineering contexts.
-
Browser-based and easy to use without installation.
Examples
-
10 decipoise = 10 × 0.0067196898 = 0.067196898 pound/foot/second.
-
50 decipoise = 50 × 0.0067196898 = 0.33598449 pound/foot/second.
Common Use Cases
-
Converting lubricant and fuel oil viscosities for industrial specifications.
-
Characterizing flow properties of food products with viscosities measured in decipoise.
-
Engineering design of pipelines and ducts using imperial viscosity units.
-
Laboratory testing and quality control where imperial units are required.
Tips & Best Practices
-
Always confirm unit system requirements before conversion to ensure compatibility.
-
Consider physical conditions such as temperature and pressure separately, as they affect viscosity.
-
Use the converter to facilitate comparison between CGS and imperial unit measurements.
-
Verify conversion results when integrating with SI-based data to avoid misinterpretation.
Limitations
-
Does not account for changes in viscosity due to temperature and pressure variations.
-
Pound/foot/second is less commonly used than pascal-second in scientific literature, requiring careful interpretation.
-
Conversion assumes steady fluid properties without dynamic changes.
Frequently Asked Questions
-
What is decipoise used for?
-
Decipoise is a unit of dynamic viscosity used mainly for specifying lubricating oils, fuel oils, and characterizing flow properties in industrial and laboratory settings.
-
Why convert decipoise to pound/foot/second?
-
Converting to pound/foot/second allows engineers and technicians to work with viscosity values in the imperial system, which is often required for US-based equipment design and testing.
-
Does this converter consider temperature effects?
-
No, temperature and pressure effects on viscosity are not included in the conversion and should be analyzed separately.
Key Terminology
-
Decipoise (dP)
-
A CGS unit of dynamic viscosity equal to one tenth of a poise, measuring fluid resistance to shear flow.
-
Pound/foot/second
-
An imperial unit of dynamic viscosity representing the internal resistance to shear flow, expressed as pound‑force second per square foot.
-
Dynamic Viscosity
-
A measure of a fluid's internal resistance to deformation and shear under applied force.
