About Calorie per Second-Square Centimeter-Celsius (cal/(s·cm²·°C))
A CGS-system unit of heat-transfer coefficient equal to exactly 41,840 W/(m²·K) — an extraordinarily large unit appropriate only for the very highest heat-transfer scenarios. Found primarily in: pre-1980s chemistry, thermochemistry, and chemical-engineering literature (Bird-Stewart-Lightfoot 'Transport Phenomena' first edition; McCabe-Smith pre-2008 editions; Soviet / Eastern-European process-engineering documentation that retained CGS units into the 1990s), older heat-exchanger research publications in J. Chem. Eng. Japan and similar, and historical-record industrial data sheets from chemical-plant nameplates installed before the 1970s SI transitions. Reference values in this unit are inconveniently small for most engineering scenarios (typical h values fall in 10⁻⁴ to 10⁻¹ cal/(s·cm²·°C) range) which is part of why W/(m²·K) and BTU/(hr·ft²·°F) displaced it. Most modern engineering has converged on W/(m²·K) (international) or BTU/(hr·ft²·°F) (US domestic). Convert cal/(s·cm²·°C) to W/(m²·K) by multiplying by 41,840.
About BTU per Hour-Square Foot-Fahrenheit (BTU/(hr·ft²·°F))
An imperial heat-transfer-coefficient unit (≈ 5.6783 W/(m²·K) per NIST SP 811). Dominant in US HVAC design, building-envelope U-factor calculations per ASHRAE 90.1, refrigeration system design, and petroleum-industry / chemical-process heat-exchanger specifications per TEMA. ASHRAE Handbook fundamentals tables list film coefficients for building surfaces in BTU/(hr·ft²·°F): indoor air still-film 1.47 BTU/(hr·ft²·°F) (the universally-cited value for interior-wall winter heating-load calculations); exterior with 15 mph wind 6.0; exterior with 7.5 mph summer wind 4.0; roof underside ~1.47-1.61 depending on emissivity. US heat-exchanger overall heat-transfer coefficients (U-values) per Perry's: water-water shell-tube 150-300 BTU/(hr·ft²·°F); steam-condensing-to-water condenser 200-1,500; refrigerant-to-air finned coil 5-15 (air-side dominant); fuel-fired furnace radiation section 1-3 (radiation-dominated). Convert BTU/(hr·ft²·°F) to W/(m²·K) by multiplying by 5.6783; to kW/(m²·K) by multiplying by 5.6783 × 10⁻³.
