Formula

Formula
kcal/(hr·m²) = cal/(cm²·s) × 35975.92

Multiply any value in calories per square centimetre-second by 35975.92 to obtain the value in kilocalories per hour-square metre.

Worked example

Convert 1 cal/(cm²·s) to kcal/(hr·m²).

  1. 01Start with 1 cal/(cm²·s).
  2. 02Multiply by the conversion factor: 1 × 35975.92 = 35975.9 kcal/(hr·m²).
Result1 cal/(cm²·s) = 35975.9 kcal/(hr·m²)

FAQ

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