How to Convert Calorie (th)/gram to Calorie (IT)/gram

Converting Calorie (th)/gram (cal (th)/g) to Calorie (IT)/gram (cal/g) is a core calculation in Specific Energy & Fuel Heating Value, which quantifies the specific energy released per unit mass of consumed fuel. Because Calorie (IT)/gram is a broader physical scale than Calorie (th)/gram, converting from cal (th)/g to cal/g condenses the numerical figure. It takes 1.000669 Calorie (th)/gram to equal a single Calorie (IT)/gram (1 cal (th)/g = 0.999331 cal/g). To convert any quantity, multiply by 0.999331 (or divide by 1.000669).

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 per kilogram (J/kg)) 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)/g = 4184 joule per kilogram (J/kg)

2. Target SI Bridge (k_target):1 cal/g = 4186.8 joule per kilogram (J/kg)

Step-by-step substitution for Calorie (th)/gram → Calorie (IT)/gram:V(cal/g) = V(cal (th)/g) × ( 4184 / 4186.8 ) = V(cal (th)/g) × 0.999331

Mathematical FormulaValue in Calorie (IT)/gram = Value in Calorie (th)/gram × 0.99933123Direct computational formula applied for standard conversion.

Worked Example

Converting 36 cal (th)/g yields an exact output of 35.975924 cal/g in Calorie (IT)/gram. Under higher industrial throughput, 240 cal (th)/g translates to 239.839496 cal/g.

Inverse check: 1 cal/g = 1.000669 cal (th)/g.
