How to Convert Pascal to Poundal/square foot

Converting Pascal (Pa) to Poundal/square foot (pdl/ft²) is a core calculation in Pressure and Stress, which measures the perpendicular force exerted by a fluid or contact load per unit surface area. 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 Pascal equals 0.671969 Poundal/square foot, while 1 pdl/ft² equals 1.488164 Pa.

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 (pascal (Pa)) 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 Pa = 1 pascal (Pa)

2. Target SI Bridge (k_target):1 pdl/ft² = 1.488164 pascal (Pa)

Step-by-step substitution for Pascal → Poundal/square foot:V(pdl/ft²) = V(Pa) × ( 1 / 1.488164 ) = V(Pa) × 0.671969

Mathematical FormulaValue in Poundal/square foot = Value in Pascal × 0.67196898Direct computational formula applied for standard conversion.

Worked Example

To convert 12 Pascal (Pa) to Poundal/square foot (pdl/ft²): multiply 12 by 0.671969 to get 8.063628 pdl/ft². At an industrial engineering scale, 240 Pa converts to 161.272554 pdl/ft².

Inverse check: 1 pdl/ft² = 1.488164 Pa.
