Factor1 kW/m² = 0.02390057 cal/(cm²·s)

Converter

kW/m²

Accepts numbers or expressions, e.g. 150 + 14.7

Result
0.0239006cal/(cm²·s)

Rendered to 6 significant figures.

Formula

Formula
cal/(cm²·s) = kW/m² × 0.02390057

Multiply any value in kilowatts per square metre by 0.02390057 to obtain the value in calories per square centimetre-second.

Worked example

Convert 1 kW/m² to cal/(cm²·s).

  1. 01Start with 1 kW/m².
  2. 02Multiply by the conversion factor: 1 × 0.02390057 = 0.0239006 cal/(cm²·s).
Result1 kW/m² = 0.0239006 cal/(cm²·s)

FAQ

What is the conversion factor from kW/m² to cal/(cm²·s)?
1 kW/m² equals 0.02390057 cal/(cm²·s). To convert, multiply the value in kilowatts per square metre by 0.02390057.
How do I convert 1 kW/m² to cal/(cm²·s)?
1 kW/m² = 0.0239006 cal/(cm²·s). For any value, multiply by 0.02390057.
How do I convert cal/(cm²·s) back to kW/m²?
Divide by the same factor — or equivalently, multiply by 41.84. So 1 cal/(cm²·s) = 41.84 kW/m².
When would I need to convert kilowatt per square metre to calorie per square centimetre-second?
Heat-flux conversions between kW/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).
