FAQ

What is the conversion factor from BTU/(hr·ft·°F) to kcal/(hr·m·K)?
1 BTU/(hr·ft·°F) equals 1.488164 kcal/(hr·m·K). To convert, multiply the value in British thermal units per hour-foot-Fahrenheit by 1.488164.
How do I convert 1 BTU/(hr·ft·°F) to kcal/(hr·m·K)?
1 BTU/(hr·ft·°F) = 1.48816 kcal/(hr·m·K). For any value, multiply by 1.488164.
How do I convert kcal/(hr·m·K) back to BTU/(hr·ft·°F)?
Divide by the same factor — or equivalently, multiply by 0.671969. So 1 kcal/(hr·m·K) = 0.671969 BTU/(hr·ft·°F).
When would I need to convert British thermal unit per hour-foot-Fahrenheit to kilocalorie per hour-metre-kelvin?
Thermal conductivity conversions between BTU/(hr·ft·°F) and kcal/(hr·m·K) are common in insulation specification, heat-exchanger design, and building-envelope analysis. SI units (W/(m·K)) appear in international standards and simulation tools, while BTU/(hr·ft·°F) is standard in US codes and vendor datasheets.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
