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 PW = 1 × 10¹⁵ watt (W)

2. Target SI Bridge (k_target):1 kcal/s = 4186.8 watt (W)

Step-by-step substitution for Petawatt → Kilocalorie (IT)/second:V(kcal/s) = V(PW) × ( 1 × 10¹⁵ / 4186.8 ) = V(PW) × 2.388459 × 10¹¹

Mathematical FormulaValue in Kilocalorie (IT)/second = Value in Petawatt × 2.38845897 × 10¹¹Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 15 PW, applying the conversion factor yields exactly 3.582688 × 10¹² kcal/s. At larger operational scale, 100 Petawatt corresponds to 2.388459 × 10¹³ kcal/s.

Inverse check: 1 kcal/s = 4.1868 × 10⁻¹² PW.
