About Kilocalorie per Kilogram-Celsius (kcal/(kg·°C))
A metric specific-heat unit numerically identical to cal/(g·°C) — since 1 kcal/kg = 1 cal/g and 1°C = 1°C. Water's specific heat is 1 kcal/(kg·°C) by the original calorie's definition. Kcal/(kg·°C) appears in some European food science, nutrition, and older chemistry literature. Identical to cal/(g·°C), so the choice between them is purely stylistic.
About BTU per Pound-Fahrenheit (BTU/(lb·°F))
An imperial specific-heat unit widely used in US HVAC, petroleum engineering, and thermodynamics. By the BTU's definition, water has a specific heat of 1 BTU/(lb·°F). US steam tables, ASHRAE HVAC calculations, and petroleum reservoir simulations all use BTU/(lb·°F). Converting to SI (×4,186.8 to get J/(kg·K)) is routine for international engineering collaboration.
