FAQ

What is the conversion factor from cal/(cm²·s·°C) to kcal/(hr·m²·°C)?
1 cal/(cm²·s·°C) equals 35975.92 kcal/(hr·m²·°C). To convert, multiply the value in calories per square centimetre-second-Celsius by 35975.92.
How do I convert 1 cal/(cm²·s·°C) to kcal/(hr·m²·°C)?
1 cal/(cm²·s·°C) = 35975.9 kcal/(hr·m²·°C). For any value, multiply by 35975.92.
How do I convert kcal/(hr·m²·°C) back to cal/(cm²·s·°C)?
Divide by the same factor — or equivalently, multiply by 2.779637e-5. So 1 kcal/(hr·m²·°C) = 2.77964e-5 cal/(cm²·s·°C).
When would I need to convert calorie per square centimetre-second-Celsius to kilocalorie per hour-square metre-Celsius?
Heat-transfer coefficient conversions between cal/(cm²·s·°C) and kcal/(hr·m²·°C) are needed in heat-exchanger sizing, boiler and condenser design, and HVAC calculations. W/(m²·K) is standard in SI engineering, and BTU/(hr·ft²·°F) is common in US heat-exchanger correlations and vendor literature.
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).
