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/s = 4.1868 watt (W)

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

Step-by-step substitution for Calorie (IT)/second → Microwatt:V(µW) = V(cal/s) × ( 4.1868 / 1 × 10⁻⁶ ) = V(cal/s) × 4186800

Mathematical FormulaValue in Microwatt = Value in Calorie (IT)/second × 4186800Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 250 cal/s, applying the conversion factor yields exactly 1.0467 × 10⁹ µW. At larger operational scale, 240 Calorie (IT)/second corresponds to 1.004832 × 10⁹ µW.

Inverse check: 1 µW = 2.388459 × 10⁻⁷ cal/s.
