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 kcal (th)/min = 69.733333 watt (W)

2. Target SI Bridge (k_target):1 W = 1 watt (W)

Step-by-step substitution for Kilocalorie (th)/minute → Watt:V(W) = V(kcal (th)/min) × ( 69.733333 / 1 ) = V(kcal (th)/min) × 69.733333

Mathematical FormulaValue in Watt = Value in Kilocalorie (th)/minute × 69.73333333Direct computational formula applied for standard conversion.

Worked Example

To convert 2.5 Kilocalorie (th)/minute (kcal (th)/min) to Watt (W): multiply 2.5 by 69.733333 to get 174.333333 W. At an industrial engineering scale, 100 kcal (th)/min converts to 6973.333333 W.

Inverse check: 1 W = 0.0143403 kcal (th)/min.
