FAQ

What is the conversion factor from kW/m² to kcal/(hr·m²)?
1 kW/m² equals 859.8452 kcal/(hr·m²). To convert, multiply the value in kilowatts per square metre by 859.8452.
How do I convert 1 kW/m² to kcal/(hr·m²)?
1 kW/m² = 859.845 kcal/(hr·m²). For any value, multiply by 859.8452.
How do I convert kcal/(hr·m²) back to kW/m²?
Divide by the same factor — or equivalently, multiply by 0.001163. So 1 kcal/(hr·m²) = 0.001163 kW/m².
When would I need to convert kilowatt per square metre to kilocalorie per hour-square metre?
Heat-flux conversions between kW/m² and kcal/(hr·m²) appear in radiative-heat-transfer analysis, furnace and reactor design, electronics cooling, and solar-energy calculations. W/m² is the SI standard; BTU/(hr·ft²) and kcal/(hr·m²) appear in US and legacy European 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).
