Konversi w per m2 k ke btu per s ft2 f
w per m2-k
The watt per meter persegi per kelvin (W/(m²·K)) adalah satuan SI dari heat transfer coefficient, juga dikenal sebagai the U-value or film coefficient. It quantifies the rate of heat transfer per unit area per unit temperature difference. Typical values range from 2–25 W/(m²·K) for free convection to over 10,000 W/(m²·K) for boiling.
btu per s-ft2-f
The British thermal unit per detik per square foot per degree Fahrenheit (Btu/(s·ft²·°F)) equals kira-kira 20,442 W/(m²·K). This high-rate imperial unit is used for intense heat transfer situations such as condensation, boiling, and rocket nozzle cooling in North American engineering.
