About Kilowatt per Square Meter-Kelvin (kW/(m²·K))

A heat-transfer-coefficient unit equal to 1,000 W/(m²·K). Used for high-performance heat-transfer situations — boiling, condensation, dropwise heat transfer, compact-heat-exchanger surfaces — where values exceed a few thousand W/(m²·K). Common in CHX (compact heat exchanger) specifications and two-phase-flow research.

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.
