kilocalorie per kilogram-Celsius
Specific heat capacityexact by definition
The kilocalorie per kilogram-Celsius is 4184 J/(kg·K) on the thermochemical calorie. Its historic appeal is that water is 1.000 of them almost exactly, which is the entire reason the calorie was defined the way it was.
Watch out: Whether water is exactly 1 depends on which calorie. On the thermochemical calorie of 4.184 J, water at 15 °C comes to 0.9995. On the 15 °C calorie it is 1 by construction. The 0.05% gap is invisible in building work and matters in calorimetry.
