As we know One Btu (IT)·in/(h·ft²·°F) is equal to 0.1442278889 W/(m·K) (1 Btu (IT)·in/(h·ft²·°F) = 0.1442278889 W/(m·K)).

To convert Btu (IT) Inch/Hour/Square Foot/Degree Fahrenheit to Watt/Meter/Kelvin, multiply your Btu (IT)·in/(h·ft²·°F) figure by 0.1442278889.

Example : convert 25 Btu (IT)·in/(h·ft²·°F) to W/(m·K):

25 Btu (IT)·in/(h·ft²·°F) = 25 × 0.1442278889 W/(m·K) = W/(m·K)

To convert Watt/Meter/Kelvin to Btu (IT) Inch/Hour/Square Foot/Degree Fahrenheit, divide your W/(m·K) figure by 0.1442278889.

Example : convert 25 W/(m·K) to Btu (IT)·in/(h·ft²·°F):

25 W/(m·K) = 25 ÷ 0.1442278889 Btu (IT)·in/(h·ft²·°F) = Btu (IT)·in/(h·ft²·°F)
