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 hW = 100 watt (W)

2. Target SI Bridge (k_target):1 cal (th)/h = 0.00116222 watt (W)

Step-by-step substitution for Hectowatt → Calorie (th)/hour:V(cal (th)/h) = V(hW) × ( 100 / 0.00116222 ) = V(hW) × 86042.06501

Mathematical FormulaValue in Calorie (th)/hour = Value in Hectowatt × 86042.06500956Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 2.5 Hectowatt (hW) produces 215105.162524 Calorie (th)/hour (cal (th)/h). In heavy-duty utility and industrial workloads, 5000 hW equals 4.302103 × 10⁸ cal (th)/h.

Inverse check: 1 cal (th)/h = 1.162222 × 10⁻⁵ hW.
