About Calorie per Second-Centimeter-Celsius (cal/(s·cm·°C))
A CGS-system unit of thermal conductivity equal to exactly 418.4 W/(m·K) — a large unit, appropriate only for highly conductive solids like pure metals at low temperatures. cal/(s·cm·°C) appears almost exclusively in: pre-1980s chemistry and physics literature (Bridgman's high-pressure thermal-conductivity measurements published 1920s-50s; Maxwell-Eucken and Bruggeman-model effective-medium thermal-conductivity papers in J. Chem. Phys.), Eastern-European and Soviet engineering documentation that retained CGS units into the 1990s, and historical-era thermochemistry textbooks. Reference values in this unit are inconveniently small for most materials (copper ~0.96 cal/(s·cm·°C); aluminum 0.57; iron 0.12; water 0.0014) which is part of why the unit fell out of favor in favor of W/(m·K). Today mostly useful for interpreting historical data and older thermochemistry papers. Convert cal/(s·cm·°C) to W/(m·K) by multiplying by 418.4.
About BTU per Hour-Foot-Fahrenheit (BTU/(hr·ft·°F))
An imperial thermal-conductivity unit (≈ 1.7307 W/(m·K) per NIST SP 811) used in US HVAC engineering, building-envelope thermal design per ASHRAE 90.1, refrigeration system design, and petroleum-engineering reservoir heat-flow analysis (steam-flood and CSS thermal EOR per SPE technical literature). Reference values in US-edition engineering handbooks: copper 231 BTU/(hr·ft·°F), steel 26, concrete 0.8, wood 0.07, fiberglass batt insulation 0.025, expanded polystyrene 0.020, aerogel 0.009. US-edition heat-transfer textbooks (Holman, Incropera-DeWitt with US-customary tables) include thermal-conductivity property tables in BTU/(hr·ft·°F) alongside W/(m·K). The unit also appears in ASHRAE Standard 90.1 prescriptive R-value tables (where R-value = thickness / k), in petroleum-reservoir simulation property cards (CMG STARS), and in pre-2000 ASHRAE Handbook editions. Convert BTU/(hr·ft·°F) to W/(m·K) by multiplying by 1.7307; to BTU·in/(hr·ft²·°F) by multiplying by 12.
