How it works

BTU/(h·ft²·°F) = W/(m²·K) ÷ 5.67826334

One BTU per hour-square foot-degree Fahrenheit is about 5.67826334 watts per square meter-kelvin, so dividing by 5.67826334 turns watts per square meter-kelvin into BTU per hour-square foot-degree Fahrenheit. For example, 1.4 W/(m²·K) is about 0.2466 BTU/(h·ft²·°F).

  1. Divide by 5.67826334 2.04 ÷ 5.67826334 = 0.36 BTU/(h·ft²·°F)
