How to Convert Pound/sq. inch to Dyne/square centimeter

Converting Pound/sq. inch (psi) to Dyne/square centimeter (dyn/cm²) 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 bridges modern MKSA metric standards with the historical Gaussian centimetre-gram-second (CGS) electrostatic and electromagnetic framework. In CGS systems, electromagnetic units (such as statvolts, abvolts, dynes, ergs, and gauss) are formulated directly from mechanical dimensions, with electrostatic-to-electromagnetic relations tied to the speed of light in vacuum (c ≈ 2.99792458 × 10¹⁰ cm/s). Exactly 1 Pound/sq. inch translates to 68947.572932 Dyne/square centimeter (1 dyn/cm² = 1.450377 × 10⁻⁵ psi).

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 psi = 6894.757293 pascal (Pa)

2. Target SI Bridge (k_target):1 dyn/cm² = 0.1 pascal (Pa)

Step-by-step substitution for Pound/sq. inch → Dyne/square centimeter:V(dyn/cm²) = V(psi) × ( 6894.757293 / 0.1 ) = V(psi) × 68947.572932

Mathematical FormulaValue in Dyne/square centimeter = Value in Pound/sq. inch × 68947.57293168Direct computational formula applied for standard conversion.

Worked Example

To convert 24 Pound/sq. inch (psi) to Dyne/square centimeter (dyn/cm²): multiply 24 by 68947.572932 to get 1654741.75036 dyn/cm². At an industrial engineering scale, 10000 psi converts to 6.894757 × 10⁸ dyn/cm².
