How to Convert BTUs per Hour-Foot-°F to BTU-Inches per Hour-Sq. Foot-°F
To convert btus per hour-foot-°f to btu-inches per hour-sq. foot-°f, multiply the thermal conductivity by the following conversion ratio: 12 btu-inches per hour-sq. foot-°f/btu per hour-foot-°f.
Since one btu per hour-foot-°f is equal to 12 btu-inches per hour-sq. foot-°f, you can use this simple formula to convert:
The thermal conductivity in btu-inches per hour-sq. foot-°f is equal to the thermal conductivity in btus per hour-foot-°f multiplied by 12.
For example, here's how to convert 5 btus per hour-foot-°f to btu-inches per hour-sq. foot-°f using the formula above.
How Many BTU-Inches per Hour-Sq. Foot-°F Are in a BTU per Hour-Foot-°F?
There are 12 btu-inches per hour-sq. foot-°f in a btu per hour-foot-°f, which is why we use this value in the formula above.
Our btu per hour-foot-°f to btu-inch per hour-sq. foot-°f calculator automatically converts your thermal conductivity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
BTUs per Hour-Foot-°F and btu-inches per hour-sq. foot-°f are both units used to measure thermal conductivity. Keep reading to learn more about each unit.
What Is a BTU per Hour-Foot-°F?
A btu per hour-foot-°f is a unit of thermal conductivity equal to 1.7307347 watts per meter-kelvin (W/(m·K)), the base unit for thermal conductivity. US HVAC thermal conductivity unit (≈ 1.7307 W/(m·K)). [1]
The btu per hour-foot-°f is classified as a US customary unit of thermal conductivity. BTUs per Hour-Foot-°F can be abbreviated as BTU/(h·ft·°F); for example, 1 btu per hour-foot-°f can be written as 1 BTU/(h·ft·°F).
When working with btus per hour-foot-°f (BTU/(h·ft·°F)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, btus per hour-foot-°f (BTU/(h·ft·°F)) are widely used across standard thermal conductivity applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a BTU-Inch per Hour-Sq. Foot-°F?
A btu-inch per hour-sq. foot-°f is a unit of thermal conductivity equal to 0.1442279 watts per meter-kelvin (W/(m·K)), the base unit for thermal conductivity. US building insulation k-factor unit (≈ 0.1442 W/(m·K)). [2]
The btu-inch per hour-sq. foot-°f is classified as a US customary unit of thermal conductivity. BTU-Inches per Hour-Sq. Foot-°F can be abbreviated as BTU·in/(h·ft²·°F); for example, 1 btu-inch per hour-sq. foot-°f can be written as 1 BTU·in/(h·ft²·°F).
When working with btu-inches per hour-sq. foot-°f (BTU·in/(h·ft²·°F)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, btu-inches per hour-sq. foot-°f (BTU·in/(h·ft²·°F)) are widely used across standard thermal conductivity applications within US customary workflows, engineering documentation, and technical data sheets.
When converting thermal conductivity between btus per hour-foot-°f (BTU/(h·ft·°F)) and btu-inches per hour-sq. foot-°f (BTU·in/(h·ft²·°F)), keep full floating-point precision (1 BTU/(h·ft·°F) = 12 BTU·in/(h·ft²·°F); 1 BTU·in/(h·ft²·°F) = 0.0833333 BTU/(h·ft·°F)) during intermediate calculations and round only the final btu-inch per hour-sq. foot-°f figure to match your instrument tolerance.
