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 (joule (J)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 thm (US) = 1.054804 × 10⁸ joule (J)
2. Target SI Bridge (ktarget):1 Cal = 4183.995381 joule (J)
Step-by-step substitution for Therm (US) → Calorie (nutritional):V(Cal) = V(thm (US)) × ( 1.054804 × 10⁸ / 4183.995381 ) = V(thm (US)) × 25210.449226
Mathematical FormulaValue in Calorie (nutritional) = Value in Therm (US) × 25210.44922627Direct computational formula applied for standard conversion.
Worked Example

To convert 24 Therm (US) (thm (US)) to Calorie (nutritional) (Cal): multiply 24 by 25210.449226 to get 605050.78143 Cal. At an industrial engineering scale, 1000 thm (US) converts to 2.521045 × 10⁷ Cal.

Inverse check: 1 Cal = 3.966609 × 10⁻⁵ thm (US).
