FAQ

What is the conversion factor from MW/m² to kcal/(hr·m²)?
1 MW/m² equals 859845.2 kcal/(hr·m²). To convert, multiply the value in megawatts per square metre by 859845.2.
How do I convert 1 MW/m² to kcal/(hr·m²)?
1 MW/m² = 859845 kcal/(hr·m²). For any value, multiply by 859845.2.
How do I convert kcal/(hr·m²) back to MW/m²?
Divide by the same factor — or equivalently, multiply by 1.163e-6. So 1 kcal/(hr·m²) = 1.163e-6 MW/m².
When would I need to convert megawatt per square metre to kilocalorie per hour-square metre?
Heat-flux conversions between MW/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).
