About BTU per Pound-Fahrenheit (BTU/(lb·°F))
An imperial specific-heat unit (≈ 4,186.8 J/(kg·K)) widely used in US HVAC, petroleum engineering, thermodynamics, and process-engineering work. By the BTU's definition (1 BTU = heat to raise 1 lb of water by 1 °F at 60 °F), water has a specific heat of exactly 1.000 BTU/(lb·°F) — numerically identical to water's value in cal/(g·°C) since both unit systems calibrate to the same physical material. US steam tables (Keenan, Keyes, Hill, Moore; Power's Steam Tables), ASHRAE Handbook fundamentals chapters on humidification + air-property calculations, petroleum-reservoir thermal-recovery simulators (CMG STARS, Computer Modelling Group), and Perry's Chemical Engineers' Handbook all default to BTU/(lb·°F) for cp / cv values. Reference values: ideal air cp = 0.240 BTU/(lb·°F), cv = 0.171 BTU/(lb·°F); structural steel 0.107 BTU/(lb·°F); aluminum 0.214 BTU/(lb·°F); typical engineering polymer 0.3-0.5 BTU/(lb·°F). Convert BTU/(lb·°F) to J/(kg·K) by multiplying by 4,186.8; to kJ/(kg·K) by multiplying by 4.187.
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 K interval = 1 °C interval. Water's specific heat is exactly 1 kcal/(kg·°C) by the original 'large calorie' (= kilocalorie) definition. kcal/(kg·°C) appears in European food-science literature (calorimetry data in EU FOSS / Codex Alimentarius food-composition databases), pre-2000 European HVAC and process-engineering documentation (especially German DIN-era specs that haven't migrated fully to J/(kg·K)), nutrition-science papers reporting metabolic-rate calculations against the 1 kcal/(kg·°C) water baseline, and older chemistry literature from Eastern Europe and Russia. The choice between cal/(g·°C) and kcal/(kg·°C) is purely a matter of which mass scale is convenient — they encode the same physical quantity with the same numerical value. Convert kcal/(kg·°C) to J/(kg·K) by multiplying by 4,184; to BTU/(lb·°F) by dividing by 1.
