FAQ

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