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 cal (th)/h = 0.00116222 watt (W)

2. Target SI Bridge (k_target):1 µW = 1 × 10⁻⁶ watt (W)

Step-by-step substitution for Calorie (th)/hour → Microwatt:V(µW) = V(cal (th)/h) × ( 0.00116222 / 1 × 10⁻⁶ ) = V(cal (th)/h) × 1162.222222

Mathematical FormulaValue in Microwatt = Value in Calorie (th)/hour × 1162.22222222Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 36 cal (th)/h, applying the conversion factor yields exactly 41840 µW. At larger operational scale, 10000 Calorie (th)/hour corresponds to 1.162222 × 10⁷ µW.

Inverse check: 1 µW = 0.000860421 cal (th)/h.
