What Is This Tool?
This converter allows you to transform surface tension measurements from poundal per inch (pdl/in), a unit used in the imperial foot–pound–second system, into gram-force per centimeter (gf/cm), a unit commonly applied in laboratory and industry settings. It facilitates accurate unit translation for comparing and reporting surface tension values across different measurement systems.

-
Reporting surface tension in FPS units and converting to cgs for laboratory analysis
-
Design and evaluation of capillary, droplet, and wetting phenomena in coating and printing industries
-
Comparing and standardizing surface tension figures across different measurement systems
-
Quality control in material, detergent, ink, and fuel formulation testing
Tips & Best Practices
-
Ensure input values are measured under consistent temperature conditions
-
Use conversions for static surface tension values; dynamic conditions may require specialized methods
-
Double-check unit selections to avoid errors in interpretation
-
Be mindful of rounding and precision when dealing with sensitive surface tension data
Limitations
-
Conversion depends on precise unit relationships; rounding errors can impact accuracy
-
Temperature variations may affect surface tension despite correct conversion
-
Only applicable to static surface tension, not dynamic interfacial tension
Frequently Asked Questions
-
What does poundal/inch [pdl/in] measure?
-
Poundal per inch measures surface tension as the force in poundals acting along a line one inch long at a liquid’s surface in the FPS system.
-
Why convert poundal/inch to gram-force/centimeter?
-
Converting allows comparison and reporting of surface tension values in units commonly used in laboratories and industries that employ cgs or SI systems.
-
Can this converter be used for dynamic surface tension?
-
No, this tool is designed for static surface tension conversions; dynamic conditions are not represented.
Key Terminology
-
Poundal per inch (pdl/in)
-
A unit of surface tension in the FPS system representing force in poundals acting per inch length at a liquid surface.
-
Gram-force per centimeter (gf/cm)
-
A unit expressing surface tension as the force of one gram-force along one centimeter, commonly used in laboratory measurements.
-
Surface Tension
-
A physical property describing the force per unit length acting along a liquid's surface or interface, causing it to resist deformation.
