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:

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 PW = 1 × 10¹⁵ watt (W)
2. Target SI Bridge (ktarget):1 kcal/h = 1.163 watt (W)
Step-by-step substitution for Petawatt → Kilocalorie (IT)/hour:V(kcal/h) = V(PW) × ( 1 × 10¹⁵ / 1.163 ) = V(PW) × 8.598452 × 10¹⁴
Mathematical FormulaValue in Kilocalorie (IT)/hour = Value in Petawatt × 8.59845228 × 10¹⁴Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 120 Petawatt (PW) produces 1.031814 × 10¹⁷ Kilocalorie (IT)/hour (kcal/h). In heavy-duty utility and industrial workloads, 1000 PW equals 8.598452 × 10¹⁷ kcal/h.

Inverse check: 1 kcal/h = 1.163 × 10⁻¹⁵ PW.
