How to Convert Joule/gram/°C to Kilocalorie (th)/kilogram/K

Converting Joule/gram/°C (J/(g·°C)) to Kilocalorie (th)/kilogram/K (kcal (th)/(kg·K)) 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 Kilocalorie (th)/kilogram/K is a broader physical scale than Joule/gram/°C, converting from J/(g·°C) to kcal (th)/(kg·K) condenses the numerical figure. It takes 4.183995 Joule/gram/°C to equal a single Kilocalorie (th)/kilogram/K (1 J/(g·°C) = 0.239006 kcal (th)/(kg·K)). To convert any quantity, multiply by 0.239006 (or divide by 4.183995).

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 J/(g·°C) = 1000 joule per kilogram kelvin (J/(kg·K))
2. Target SI Bridge (ktarget):1 kcal (th)/(kg·K) = 4183.995381 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for Joule/gram/°C → Kilocalorie (th)/kilogram/K:V(kcal (th)/(kg·K)) = V(J/(g·°C)) × ( 1000 / 4183.995381 ) = V(J/(g·°C)) × 0.239006
Mathematical FormulaValue in Kilocalorie (th)/kilogram/K = Value in Joule/gram/°C × 0.239006Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 8 J/(g·°C), applying the conversion factor yields exactly 1.912048 kcal (th)/(kg·K). At larger operational scale, 1000 Joule/gram/°C corresponds to 239.006 kcal (th)/(kg·K).

Inverse check: 1 kcal (th)/(kg·K) = 4.183995 J/(g·°C).
