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 (watt (W)) 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 GW = 1 × 10⁹ watt (W)

2. Target SI Bridge (k_target):1 kcal/h = 1.163 watt (W)

Step-by-step substitution for Gigawatt → Kilocalorie (IT)/hour:V(kcal/h) = V(GW) × ( 1 × 10⁹ / 1.163 ) = V(GW) × 8.598452 × 10⁸

Mathematical FormulaValue in Kilocalorie (IT)/hour = Value in Gigawatt × 8.59845228 × 10⁸Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Gigawatt (GW) to Kilocalorie (IT)/hour (kcal/h): multiply 50 by 8.598452 × 10⁸ to get 4.299226 × 10¹⁰ kcal/h. At an industrial engineering scale, 100 GW converts to 8.598452 × 10¹⁰ kcal/h.

Inverse check: 1 kcal/h = 1.163 × 10⁻⁹ GW.
