FAQ

What is the conversion factor from cal/(cm²·s·°C) to kJ/(h·m²·K)?
1 cal/(cm²·s·°C) equals 150624 kJ/(h·m²·K). To convert, multiply the value in calories per square centimetre-second-Celsius by 150624.
How do I convert 1 cal/(cm²·s·°C) to kJ/(h·m²·K)?
1 cal/(cm²·s·°C) = 150624 kJ/(h·m²·K). For any value, multiply by 150624.
How do I convert kJ/(h·m²·K) back to cal/(cm²·s·°C)?
Divide by the same factor — or equivalently, multiply by 6.639048e-6. So 1 kJ/(h·m²·K) = 6.63905e-6 cal/(cm²·s·°C).
When would I need to convert calorie per square centimetre-second-Celsius to kilojoule per hour-square metre-kelvin?
Heat-transfer coefficient conversions between cal/(cm²·s·°C) and kJ/(h·m²·K) 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).
