What Is This Tool?
This unit converter allows you to switch dynamic viscosity values from gram per centimeter per second, a cgs metric unit, to pound-force second per square inch, which is used in Imperial and US customary systems. It helps facilitate data interpretation between these two unit systems in various technical fields.
How to Use This Tool?

Browser-based and easy to use without installation
-
Enables comparison of legacy US customary viscosity data with modern metric measurements
Examples
-
10 Gram/centimeter/second = 10 × 0.0000145038 = 0.000145038 Pound-force second/sq. inch
-
100 Gram/centimeter/second = 100 × 0.0000145038 = 0.00145038 Pound-force second/sq. inch
Common Use Cases
-
Characterizing lubricants and greases in tribology and mechanical design
-
Performing rheological assessments of polymer melts and industrial fluids
-
Quality control of viscous food products like syrups and sauces
-
Reporting viscosity of heavy oils or bitumen in US customary engineering contexts
-
Interpreting legacy technical data involving psi-based viscosity units
Tips & Best Practices
-
Ensure correct unit selection before converting
-
Use this conversion for translating between metric cgs and Imperial systems
-
Double-check values when dealing with very large or small viscosities due to magnitude differences
-
When handling legacy data in psi·s, verify conversions for modern SI compatibility
-
Apply conversions carefully in sensitive rheological analyses to avoid rounding errors
Limitations
-
Significant figure caution is necessary owing to large differences in unit magnitude
-
Legacy viscosity data may introduce rounding errors when converted
-
Conversion precision may affect sensitive rheological test interpretations
Frequently Asked Questions
-
What does gram/centimeter/second measure?
-
Gram per centimeter per second is a cgs unit measuring dynamic viscosity, representing a fluid's resistance to shear flow.
-
When should I use pound-force second per square inch?
-
Use this unit mainly in US customary engineering contexts to express viscosity of thick greases, heavy oils, or bitumen.
-
Is the conversion between these units exact?
-
The tool uses a defined conversion rate, but rounding and magnitude differences mean care is needed for very precise work.
