About Joule per Kilogram-Kelvin (J/(kg·K))
The SI unit of specific heat capacity — the energy needed to raise the temperature of 1 kg of material by 1 K. J/(kg·K) is the universal unit in thermodynamics and heat-transfer analysis. Water's specific heat, the highest of any common substance, is 4,186 J/(kg·K); air is about 1,005 J/(kg·K); most metals are 400–900 J/(kg·K). Every CFD solver, HVAC sizing tool, and thermal-mass calculation uses J/(kg·K) internally.
About Calorie per Gram-Celsius (cal/(g·°C))
A CGS specific-heat unit historically used in chemistry and food science. By the original definition of the calorie, water has a specific heat of exactly 1 cal/(g·°C) — the basis on which both the unit and the property coevolved. Numerically identical to kcal/(kg·°C). Chemistry textbooks and nutrition science papers from the 20th century frequently reported specific heats in this unit, and calorimetry experiments in education still use it.
