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:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 kWh/kg = 3599999.99712 joule per kilogram (J/kg)
2. Target SI Bridge (ktarget):1 cal/g = 4184.000002 joule per kilogram (J/kg)
Step-by-step substitution for Kilowatt hour/kilogram → Calorie/gram:V(cal/g) = V(kWh/kg) × ( 3599999.99712 / 4184.000002 ) = V(kWh/kg) × 860.420649
Mathematical FormulaValue in Calorie/gram = Value in Kilowatt hour/kilogram × 860.42064891Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Kilowatt hour/kilogram (kWh/kg) to Calorie/gram (cal/g): multiply 120 by 860.420649 to get 103250.477869 cal/g. At an industrial engineering scale, 100 kWh/kg converts to 86042.064891 cal/g.

Inverse check: 1 cal/g = 0.00116222 kWh/kg.
