About Watt per Square Meter-Kelvin (W/(m²·K))
The SI unit of heat-transfer coefficient h — the constant of proportionality between heat flux and temperature difference in Newton's law of cooling (q = h·ΔT). W/(m²·K) is the universal unit in heat-exchanger design and HVAC. Typical values: natural convection air ~5–25 W/(m²·K); forced-air 25–250; boiling water 2,500–100,000; filmwise condensation 5,000–15,000.
About Kilocalorie per Hour-Square Meter-Celsius (kcal/(hr·m²·°C))
A legacy metric unit of heat-transfer coefficient (1 kcal/(hr·m²·°C) = 1.163 W/(m²·K)) that persists in older European engineering literature — particularly German, French, and Italian HVAC and process-plant documentation from before SI was fully adopted. Still occasionally seen on older heat-exchanger nameplates.
