About BTU per Hour-Square Foot-Fahrenheit (BTU/(hr·ft²·°F))
An imperial heat-transfer-coefficient unit (1 BTU/(hr·ft²·°F) ≈ 5.678 W/(m²·K)). Dominant in US HVAC design, building-envelope calculations, and petroleum-industry heat-exchanger specifications. ASHRAE fundamentals tables list film coefficients for building surfaces in BTU/(hr·ft²·°F) — e.g., indoor air film is ~1.47, exterior with 15 mph wind is ~6.0.
About Calorie per Second-Square Centimeter-Celsius (cal/(s·cm²·°C))
A CGS unit of heat-transfer coefficient (= 41,840 W/(m²·K)) mostly found in older chemistry and thermochemistry literature. Very large unit; rarely used today because most engineering has converged on W/(m²·K) or BTU/(hr·ft²·°F).
