A heat-transfer-coefficient unit equal to exactly 1,000 W/(m²·K). Used for high-performance heat-transfer applications where W/(m²·K) values become inconveniently large: nucleate-boiling and two-phase-flow heat transfer (saturated nucleate pool boiling of water at 1 atm reaches 50-100 kW/(m²·K) near critical heat flux per Rohsenow correlation), dropwise condensation surfaces (advanced superhydrophobic coatings achieve 100-200 kW/(m²·K) per Nature Materials research on slippery liquid-infused porous surfaces, SLIPS), compact heat exchanger (CHX) surface effectiveness in cryogenic processing and aerospace (printed-circuit heat exchangers Heatric / Velocys / Vacuum Process Engineering achieve 5-15 kW/(m²·K) overall U), Falling-film evaporators in refrigeration and desalination (MSF and MED plants), and microchannel cooling research for power-electronics thermal management. Convert kW/(m²·K) to W/(m²·K) by multiplying by 1,000; to BTU/(hr·ft²·°F) by multiplying by 176.1.
