How to Convert Joule/kilogram celsius to Calorie/gram celsius

Converting Joule/kilogram celsius (J/(kg·°C)) to Calorie/gram celsius (cal/(g·°C)) 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/gram celsius is a broader physical scale than Joule/kilogram celsius, converting from J/(kg·°C) to cal/(g·°C) condenses the numerical figure. It takes 4184.000002 Joule/kilogram celsius to equal a single Calorie/gram celsius (1 J/(kg·°C) = 0.000239006 cal/(g·°C)). To convert any quantity, multiply by 0.000239006 (or divide by 4184.000002).

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:

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 J/(kg·°C) = 1 joule per kilogram kelvin (J/(kg·K))

2. Target SI Bridge (k_target):1 cal/(g·°C) = 4184.000002 joule per kilogram kelvin (J/(kg·K))

Step-by-step substitution for Joule/kilogram celsius → Calorie/gram celsius:V(cal/(g·°C)) = V(J/(kg·°C)) × ( 1 / 4184.000002 ) = V(J/(kg·°C)) × 0.000239006
