Formula

Formula
W/cm² = cal/(cm²·s) × 4.184

Multiply any value in calories per square centimetre-second by 4.184 to obtain the value in watts per square centimetre.

Worked example

Convert 1 cal/(cm²·s) to W/cm².

  1. 01Start with 1 cal/(cm²·s).
  2. 02Multiply by the conversion factor: 1 × 4.184 = 4.184 W/cm².
Result1 cal/(cm²·s) = 4.184 W/cm²

FAQ

What is the conversion factor from cal/(cm²·s) to W/cm²?
1 cal/(cm²·s) equals 4.184 W/cm². To convert, multiply the value in calories per square centimetre-second by 4.184.
How do I convert 1 cal/(cm²·s) to W/cm²?
1 cal/(cm²·s) = 4.184 W/cm². For any value, multiply by 4.184.
How do I convert W/cm² back to cal/(cm²·s)?
Divide by the same factor — or equivalently, multiply by 0.2390057. So 1 W/cm² = 0.239006 cal/(cm²·s).
When would I need to convert calorie per square centimetre-second to watt per square centimetre?
Heat-flux conversions between cal/(cm²·s) and W/cm² 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).
