How to Convert Kilojoule/kilogram/K to Calorie (IT)/gram/°F

Converting Kilojoule/kilogram/K (kJ/(kg·K)) to Calorie (IT)/gram/°F (cal/(g·°F)) is a core calculation in Specific Heat Capacity, which measures the thermal energy required to raise the temperature of a unit mass of substance by one degree. Because Calorie (IT)/gram/°F is a broader physical scale than Kilojoule/kilogram/K, converting from kJ/(kg·K) to cal/(g·°F) condenses the numerical figure. It takes 2.326 Kilojoule/kilogram/K to equal a single Calorie (IT)/gram/°F (1 kJ/(kg·K) = 0.429923 cal/(g·°F)). To convert any quantity, multiply by 0.429923 (or divide by 2.326).

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 kelvin (J/(kg·K))) 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 kJ/(kg·K) = 1000 joule per kilogram kelvin (J/(kg·K))
2. Target SI Bridge (ktarget):1 cal/(g·°F) = 2326 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for Kilojoule/kilogram/K → Calorie (IT)/gram/°F:V(cal/(g·°F)) = V(kJ/(kg·K)) × ( 1000 / 2326 ) = V(kJ/(kg·K)) × 0.429923
Mathematical FormulaValue in Calorie (IT)/gram/°F = Value in Kilojoule/kilogram/K × 0.42992261Direct computational formula applied for standard conversion.
Worked Example

To convert 120 Kilojoule/kilogram/K (kJ/(kg·K)) to Calorie (IT)/gram/°F (cal/(g·°F)): multiply 120 by 0.429923 to get 51.590714 cal/(g·°F). At an industrial engineering scale, 240 kJ/(kg·K) converts to 103.181427 cal/(g·°F).

Inverse check: 1 cal/(g·°F) = 2.326 kJ/(kg·K).
