How to Convert Bar to Poundal/square foot

Converting Bar (bar) 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 Bar equals 67196.897514 Poundal/square foot, while 1 pdl/ft² equals 1.488164 × 10⁻⁵ bar.

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 bar = 100000 pascal (Pa)

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

Step-by-step substitution for Bar → Poundal/square foot:V(pdl/ft²) = V(bar) × ( 100000 / 1.488164 ) = V(bar) × 67196.897514

Mathematical FormulaValue in Poundal/square foot = Value in Bar × 67196.89751395Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 15 bar, applying the conversion factor yields exactly 1007953.462709 pdl/ft². At larger operational scale, 240 Bar corresponds to 1.612726 × 10⁷ pdl/ft².

Inverse check: 1 pdl/ft² = 1.488164 × 10⁻⁵ bar.
