What Is This Tool?
This tool enables conversion between the dynamic viscosity unit poundal second per square foot, used mainly in older imperial systems, and picopoise, a very small unit derived from poise. It helps translate viscosity values across vastly different measurement scales for engineering and scientific purposes.
How to Use This Tool?
-
Enter the numerical value in poundal second per square foot you want to convert.
-
Select the target unit as picopoise [pP].
-
Click the convert button to get the equivalent viscosity in picopoise.
-
Review the converted result expressed at a very fine viscosity scale.
Key Features
-
Converts from poundal second/square foot to picopoise with a precise fixed factor.
-
Supports viscosity measurements used in both imperial and CGS unit systems.
-
Ideal for converting legacy experimental data to modern, fine-scale units.
-
Browser-based and simple to use without requiring advanced knowledge.
Examples
-
2 poundal second/square foot = 29763278871370 picopoise [pP]
-
0.5 poundal second/square foot = 7440819717842.5 picopoise [pP]
Common Use Cases
-
Calculating viscosities of lubricants and oils in older FPS or imperial engineering contexts.
-
Converting dynamic viscosity values for molecular-dynamics simulations of nanoscale lubricants and gases.
-
Analyzing low-viscosity rarefied gas flows in microfluidic and laboratory research.
-
Interpreting historical FPS-unit viscosity data and comparing it with modern CGS or SI measurements.
Tips & Best Practices
-
Double-check input values to prevent errors caused by the large magnitude of conversion.
-
Use this conversion primarily when working with legacy FPS units or very low viscosities.
-
Be aware of potential numerical overflow and maintain proper precision during calculations.
-
Confirm the relevance of the unit scales for your specific scientific or engineering application.
Limitations
-
The huge conversion factor can lead to loss of precision or overflow in some calculation tools.
-
Poundal second/square foot is mostly obsolete outside legacy or niche imperial unit contexts.
-
Picopoise applies mostly to extremely low viscosities and is less common in general industrial use.
-
The conversion links units representing vastly different dynamic viscosity scales.
Frequently Asked Questions
-
What does poundal second per square foot measure?
-
It measures dynamic (absolute) viscosity quantifying a fluid's resistance to shear flow using imperial FPS units, defined as force times time over area.
-
Why use picopoise for viscosity?
-
Picopoise is a CGS-derived submultiple of poise designed for measuring extremely low viscosities, useful in molecular-scale and high-precision fluid studies.
-
Can I convert any viscosity unit using this tool?
-
This tool specifically converts from poundal second per square foot to picopoise and does not support other viscosity unit conversions.
Key Terminology
-
Poundal second per square foot
-
An imperial dynamic viscosity unit quantifying fluid resistance to shear by applying one poundal force over one second per square foot area.
-
Picopoise
-
A CGS submultiple of the poise used to measure extremely low dynamic viscosities, equal to 10⁻¹² poise or 1.0×10⁻¹³ pascal-second.
-
Dynamic (absolute) viscosity
-
A measurement of a fluid's resistance to shear flow or deformation under applied force.
