FAQ

What is the conversion factor from BTU·in/(hr·ft²·°F) to kW/(m·K)?
1 BTU·in/(hr·ft²·°F) equals 0.0001442279 kW/(m·K). To convert, multiply the value in British thermal unit-inches per hour-square foot-Fahrenheit by 0.0001442279.
How do I convert 1 BTU·in/(hr·ft²·°F) to kW/(m·K)?
1 BTU·in/(hr·ft²·°F) = 0.000144228 kW/(m·K). For any value, multiply by 0.0001442279.
How do I convert kW/(m·K) back to BTU·in/(hr·ft²·°F)?
Divide by the same factor — or equivalently, multiply by 6933.471. So 1 kW/(m·K) = 6933.47 BTU·in/(hr·ft²·°F).
When would I need to convert British thermal unit-inch per hour-square foot-Fahrenheit to kilowatt per metre-kelvin?
Thermal conductivity conversions between BTU·in/(hr·ft²·°F) and kW/(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).
