FAQ

What is the conversion factor from BTU·in/(hr·ft²·°F) to cal/(cm·s·°C)?
1 BTU·in/(hr·ft²·°F) equals 0.000344713 cal/(cm·s·°C). To convert, multiply the value in British thermal unit-inches per hour-square foot-Fahrenheit by 0.000344713.
How do I convert 1 BTU·in/(hr·ft²·°F) to cal/(cm·s·°C)?
1 BTU·in/(hr·ft²·°F) = 0.000344713 cal/(cm·s·°C). For any value, multiply by 0.000344713.
How do I convert cal/(cm·s·°C) back to BTU·in/(hr·ft²·°F)?
Divide by the same factor — or equivalently, multiply by 2900.964. So 1 cal/(cm·s·°C) = 2900.96 BTU·in/(hr·ft²·°F).
When would I need to convert British thermal unit-inch per hour-square foot-Fahrenheit to calorie per centimetre-second-Celsius?
Thermal conductivity conversions between BTU·in/(hr·ft²·°F) and cal/(cm·s·°C) 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).
