How to Convert Poundal/inch to Gram-force/centimeter

Converting Poundal/inch (pdl/in) to Gram-force/centimeter (gf/cm) is a core calculation in Surface Tension, which measures the cohesive tensile force per unit length acting along the surface boundary of a liquid. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Poundal/inch equals 5.57224 Gram-force/centimeter, while 1 gf/cm equals 0.179461 pdl/in.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (newton per meter (N/m)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 pdl/in = 5.464481 newton per meter (N/m)

2. Target SI Bridge (k_target):1 gf/cm = 0.980661 newton per meter (N/m)

Step-by-step substitution for Poundal/inch → Gram-force/centimeter:V(gf/cm) = V(pdl/in) × ( 5.464481 / 0.980661 ) = V(pdl/in) × 5.57224

Worked Example

Evaluating an input of 2.5 Poundal/inch (pdl/in) produces 13.930601 Gram-force/centimeter (gf/cm). In heavy-duty utility and industrial workloads, 480 pdl/in equals 2674.67541 gf/cm.

Inverse check: 1 gf/cm = 0.179461 pdl/in.
