About Watt per Square Meter-Kelvin (W/(m²·K))
The SI unit of convective heat-transfer coefficient h (ISO 80000-5 §5-11) — the constant of proportionality between surface heat flux and the fluid-to-surface temperature difference in Newton's law of cooling (q = h·ΔT). W/(m²·K) is the universal working unit in heat-exchanger thermal design (shell-and-tube per TEMA standards, plate-frame per ALPEMA, brazed-aluminum-plate-fin per ALPEMA), HVAC system design (per ASHRAE Handbook fundamentals chapters), boiler and condenser sizing per ASME Section VIII, refrigeration evaporator and condenser design, and electronics-cooling thermal analysis. Reference values from Incropera-DeWitt 'Fundamentals of Heat and Mass Transfer' Table 1.1: natural convection in air 2-25 W/(m²·K) (dominant resistance in building envelopes); forced-convection air 25-250 W/(m²·K) (HVAC ducts, cooling fans); natural convection water 50-1,000 W/(m²·K); forced-convection water 100-20,000 W/(m²·K); boiling water 2,500-100,000 W/(m²·K) (nucleate-boiling regime, with critical heat flux at ~1 MW/m²); filmwise condensation 5,000-15,000 W/(m²·K); dropwise condensation 30,000-150,000 W/(m²·K) — 10× higher than filmwise, exploited in advanced condenser surface treatments. Also called the 'film coefficient' in older HVAC literature.
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.
