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 (joule per kilogram (J/kg)) 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 kWh/kg = 3599999.99712 joule per kilogram (J/kg)

2. Target SI Bridge (k_target):1 kcal/kg = 4184.000002 joule per kilogram (J/kg)

Step-by-step substitution for Kilowatt hour/kilogram → Kilocalorie/kilogram:V(kcal/kg) = V(kWh/kg) × ( 3599999.99712 / 4184.000002 ) = V(kWh/kg) × 860.420649

Mathematical FormulaValue in Kilocalorie/kilogram = Value in Kilowatt hour/kilogram × 860.42064891Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 8 kWh/kg, applying the conversion factor yields exactly 6883.365191 kcal/kg. At larger operational scale, 10000 Kilowatt hour/kilogram corresponds to 8604206.489117 kcal/kg.

Inverse check: 1 kcal/kg = 0.00116222 kWh/kg.
