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 kJ/h = 0.277778 watt (W)

2. Target SI Bridge (k_target):1 dW = 0.1 watt (W)

Step-by-step substitution for Kilojoule/hour → Deciwatt:V(dW) = V(kJ/h) × ( 0.277778 / 0.1 ) = V(kJ/h) × 2.777778

Mathematical FormulaValue in Deciwatt = Value in Kilojoule/hour × 2.77777778Direct computational formula applied for standard conversion.

Worked Example

To convert 2.5 Kilojoule/hour (kJ/h) to Deciwatt (dW): multiply 2.5 by 2.777778 to get 6.944444 dW. At an industrial engineering scale, 100 kJ/h converts to 277.777778 dW.

Inverse check: 1 dW = 0.36 kJ/h.
