How to Convert BTU/Hour-Foot-°F to BTU-Inch/Hour-sq Foot-°F

To convert from BTU/Hour-Foot-°F (BTU/(h·ft·°F)) to BTU-Inch/Hour-sq Foot-°F (BTU·in/(h·ft²·°F)), multiply the value by 11.9999999945.

Formula: BTU·in/(h·ft²·°F) = BTU/(h·ft·°F) × 11.9999999945

Reverse: BTU/(h·ft·°F) = BTU·in/(h·ft²·°F) × 0.0833333334

Step-by-Step Example

Start with your value in BTU/Hour-Foot-°F. For example: 5 BTU/(h·ft·°F)
Multiply by the conversion factor: 5 x 11.9999999945
The result is: 60 BTU·in/(h·ft²·°F)
