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 kgf/mm² = 9806650 pascal (Pa)

2. Target SI Bridge (k_target):1 atm = 101325 pascal (Pa)

Step-by-step substitution for Kilogram-force/sq. mm → Standard Atmosphere:V(atm) = V(kgf/mm²) × ( 9806650 / 101325 ) = V(kgf/mm²) × 96.784111
