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 Calorie per Gram-Celsius (cal/(g·°C))
A CGS-system specific-heat unit historically central to chemistry, food science, and biochemistry. By the original 1824 definition of the calorie (the energy needed to raise 1 g of water by 1 °C at 14.5-15.5 °C), water has a specific heat of exactly 1.000 cal/(g·°C) — the basis on which both the unit and the water-specific-heat property coevolved. Numerically identical to kcal/(kg·°C) since both ratios scale the same way. Used heavily in: pre-1990s chemistry textbooks (Atkins, McMurry, Solomons), nutrition-science papers, calorimetry-experiment education (Differential Scanning Calorimetry DSC instruments per ASTM E1269 still produce data convertible to cal/(g·°C) units for legacy comparison), pharmaceutical excipient characterization in older USP monographs, and food-energy / bomb-calorimetry research per AOAC Official Methods 968.06. Convert cal/(g·°C) to J/(kg·K) by multiplying by 4,184; to BTU/(lb·°F) by dividing by 1 (they're numerically identical since both calibrate to water = 1).
