Convert International table calorie per gram per degree Celsius (cal(IT)/(g·°C)) to Joule per kilogram kelvin (J/(kg·K)) instantly and accurately.
Conversion Formula
J/(kg·K) = cal(IT)/(g·°C) × 4186.8
About International table calorie per gram per degree Celsius
The international table calorie per gram per degree Celsius (cal(IT)/(g·°C)) equals exactly 4186.8 J/(kg·K) (1 cal(IT) = 4.1868 J). Standard in steam tables, international thermodynamic references, and pre-SI calorimetry. Slightly larger than the thermochemical variant. Water: 1 cal(IT)/(g·°C) at ≈15 °C. 1 cal(IT)/(g·°C) = 4186.8 J/(kg·K) = 1 kcal(IT)/(kg·°C).
About Joule per kilogram kelvin
The joule per kilogram kelvin (J/(kg·K)) is the SI coherent unit for specific heat capacity, defined by the relation Q = mcΔT. Water ≈4182, iron ≈449, aluminium ≈897, copper ≈385, glass ≈840 J/(kg·K). Referenced in ISO 31-4 and all major international standards. 1 J/(kg·K) = 1 J/(kg·°C) = 10⁻³ kJ/(kg·K).
