What Is This Tool?
This tool converts dynamic viscosity measurements from decipoise (dP), a CGS unit commonly used for lubricants and food products, to terapoise (TP), a much larger CGS-based unit applied in fields like geophysics and materials science for measuring extremely high viscosities.
How to Use This Tool?
-
Enter the value in decipoise (dP) that you want to convert
-
Select decipoise (dP) as the source unit and terapoise (TP) as the target unit
-
Click the convert button to get the equivalent value in terapoise (TP)
Key Features
-
Converts viscosity from decipoise (dP) to terapoise (TP) with a precise scaling factor
-
Supports unit comparison between small-scale laboratory viscometry and large-scale geophysical or material science applications
-
Includes clear definitions and typical use cases for both units
-
Browser-based and easy to use without installation
Examples
-
10 decipoise (dP) equals 1 × 10⁻¹² terapoise (TP)
-
50 decipoise (dP) equals 5 × 10⁻¹² terapoise (TP)
Common Use Cases
-
Comparing small-scale viscosity measurements in laboratory fluids to very large viscosity values in geophysics
-
Studying the viscosity of highly cross-linked polymer systems near solidification
-
Scaling viscosity values in materials science and theoretical rheology involving extremely viscous materials
Tips & Best Practices
-
Use this conversion primarily for theoretical or comparative purposes due to the large scaling difference
-
Double-check units when interpreting extremely small terapoise results from decipoise inputs
-
Apply this tool to relate industrial or laboratory viscosities to geophysical or material science contexts
Limitations
-
Direct practical conversions are uncommon because of the enormous difference in scale between decipoise and terapoise
-
Terapoise values correspond to extremely viscous or almost solid-like materials, not typical for everyday fluids
-
Conversion precision may decrease when very small decipoise values are converted due to the tiny scaling factor
Frequently Asked Questions
-
What is decipoise used for?
-
Decipoise is used to specify viscosities of lubricating oils, fuel oils, and to characterize flow properties of food products such as syrups and honey.
-
When should I convert viscosity to terapoise?
-
Converting to terapoise is helpful when dealing with extremely high viscosity values in fields like geophysics or materials science, especially for comparative or theoretical analyses.
-
Why is the conversion factor between decipoise and terapoise so small?
-
Because 1 terapoise equals 10¹² poise, and decipoise is one tenth of a poise, the scaling factor is extremely large, making the conversion factor 1 × 10⁻¹³.
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; equivalent to 0.01 pascal-second.
-
Terapoise (TP)
-
A metric multiple of the poise equal to 10¹² poise or 10¹¹ pascal-seconds, used for measuring extremely large dynamic viscosities.
-
Dynamic Viscosity
-
A measure of a fluid's internal resistance to flow under shear stress.
