W/(cm²·K)
watt per square centimeter kelvin
Heat transfer coefficientexact by definition
The watt per square centimeter kelvin is exactly 10⁴ W/(m²·K). Electronics cooling uses it because the areas are small and the coefficients are large: a microchannel cold plate reaches 1 to 5 W/(cm²·K), where natural convection in air is 0.001.
