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 (J)) 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 MWh = 3.6 × 10⁹ joule (J)
2. Target SI Bridge (ktarget):1 Cal = 4183.995381 joule (J)
Step-by-step substitution for Megawatt-hour → Calorie (nutritional):V(Cal) = V(MWh) × ( 3.6 × 10⁹ / 4183.995381 ) = V(MWh) × 860421.6
Mathematical FormulaValue in Calorie (nutritional) = Value in Megawatt-hour × 860421.6Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 MWh, applying the conversion factor yields exactly 3.097518 × 10⁷ Cal. At larger operational scale, 2500 Megawatt-hour corresponds to 2.151054 × 10⁹ Cal.

Inverse check: 1 Cal = 1.162221 × 10⁻⁶ MWh.
