FAQ
What is the conversion factor from kcal/(hr·m²) to cal/(cm²·s)?
1 kcal/(hr·m²) equals 2.779637e-5 cal/(cm²·s). To convert, multiply the value in kilocalories per hour-square metre by 2.779637e-5.
How do I convert 1 kcal/(hr·m²) to cal/(cm²·s)?
1 kcal/(hr·m²) = 2.77964e-5 cal/(cm²·s). For any value, multiply by 2.779637e-5.
How do I convert cal/(cm²·s) back to kcal/(hr·m²)?
Divide by the same factor — or equivalently, multiply by 35975.92. So 1 cal/(cm²·s) = 35975.9 kcal/(hr·m²).
When would I need to convert kilocalorie per hour-square metre to calorie per square centimetre-second?
Heat-flux conversions between kcal/(hr·m²) and cal/(cm²·s) 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).
