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

Converting Gram-force/centimeter (gf/cm) to Poundal/inch (pdl/in) 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 Gram-force/centimeter equals 0.179461 Poundal/inch, while 1 pdl/in equals 5.57224 gf/cm.

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 gf/cm = 0.980661 newton per meter (N/m)

2. Target SI Bridge (k_target):1 pdl/in = 5.464481 newton per meter (N/m)

Step-by-step substitution for Gram-force/centimeter → Poundal/inch:V(pdl/in) = V(gf/cm) × ( 0.980661 / 5.464481 ) = V(gf/cm) × 0.179461

Mathematical FormulaValue in Poundal/inch = Value in Gram-force/centimeter × 0.17946103Direct computational formula applied for standard conversion.

Worked Example

Converting 8 gf/cm yields an exact output of 1.435688 pdl/in in Poundal/inch. Under higher industrial throughput, 100 gf/cm translates to 17.946103 pdl/in.

Inverse check: 1 pdl/in = 5.57224 gf/cm.
