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.
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.
