$BTU_{th}$ Inch per Square Foot Hour Degree Fahrenheit is an Imperial unit for 'Thermal Conductivity' expressed as $Btu_{it}-in/(h-ft^{2}-degF)$. An International British thermal unit inch per second per square foot per degree Fahrenheit is a unit of thermal conductivity in the US Customary Units and British Imperial Units. $1\,Btu_{it} \cdot in/(h \cdot ft^{2} \cdot degF)$ shows that one thermochemical BTU of heat per one hour moves through one square foot of material, which is one foot thick due to a temperature difference of one degree Fahrenheit.
