What Is This Tool?

This converter allows you to change dynamic viscosity values from pound-force second per square inch, a US customary unit, into terapoise, a very large metric unit used for expressing extremely high viscosity. It is ideal for comparing engineering data to scientific metrics in fields like polymer processing and geophysics.

How to Use This Tool?

  • Enter the dynamic viscosity value in pound-force second per square inch.
  • Select pound-force second/sq. inch as the input unit.
  • Choose terapoise [TP] as the output unit.
  • Click the convert button to obtain the equivalent viscosity value in terapoise.
  • Review the result, which may be a very small number expressed in scientific notation.

Key Features

  • Converts viscosity from pound-force second per square inch to terapoise.
  • Based on precise conversion formulas relating US customary and metric units.
  • Supports processing of extremely large viscosity values common in scientific research.
  • Browser-based and easy to use without additional software.

Examples

  • Convert 10 pound-force second/sq. inch to terapoise: 10 × 6.8947572931684e-8 = 6.8947572931684e-7 TP.
  • Convert 0.5 pound-force second/sq. inch to terapoise: 0.5 × 6.8947572931684e-8 = 3.4473786465842e-8 TP.

Common Use Cases

  • Reporting very thick greases, heavy oils, or bitumen viscosity using US customary units.
  • Describing polymer melts and adhesives properties in industrial specifications that use psi-based measurements.
  • Translating legacy technical data to metric viscosity scales for scientific analysis.
  • Expressing extremely large viscosities in geophysics and planetary science research.
  • Characterizing highly viscous materials near solidification in materials science.

Tips & Best Practices

  • Use scientific notation when interpreting converted values due to the large scale difference.
  • Confirm the unit context before conversion to ensure appropriate application of terapoise values.
  • Cross-check legacy data when converting from pound-force second/sq. inch for accuracy.
  • Apply conversion for research scenarios involving very high-viscosity substances.

Limitations

  • Converted values are extremely small, which might be difficult to interpret without proper notation.
  • Terapoise values are suited only for extraordinarily high viscosity contexts and are uncommon in typical engineering settings.

Frequently Asked Questions

What does pound-force second per square inch measure?
It measures dynamic viscosity in the Imperial/US customary system, relating shear stress to shear rate for thick fluids.

Why would I need to convert to terapoise?
Terapoise is useful for expressing extremely large viscosity values in scientific fields like geophysics and materials science.

Can this converter be used for routine engineering viscosity measurements?
Generally no, because terapoise represents very large viscosity values, which are uncommon in everyday engineering.

Key Terminology

Pound-force second per square inch
An Imperial/US customary unit of dynamic viscosity relating shear stress to shear rate, used in engineering contexts.
Terapoise
A metric unit equal to 10^12 poise, used to quantify extremely high dynamic viscosities.
Dynamic (absolute) viscosity
A measure of a fluid's resistance to shear flow, indicating internal friction.
