FAQ

What is the conversion factor from cal/(cm²·s) to W/m²?
1 cal/(cm²·s) equals 41840 W/m². To convert, multiply the value in calories per square centimetre-second by 41840.
How do I convert 1 cal/(cm²·s) to W/m²?
1 cal/(cm²·s) = 41840 W/m². For any value, multiply by 41840.
How do I convert W/m² back to cal/(cm²·s)?
Divide by the same factor — or equivalently, multiply by 2.390057e-5. So 1 W/m² = 2.39006e-5 cal/(cm²·s).
When would I need to convert calorie per square centimetre-second to watt per square metre?
Heat-flux conversions between cal/(cm²·s) and W/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).
