Formula

Formula
MW/m² = kcal/(hr·m²) × 1.163e-6

Multiply any value in kilocalories per hour-square metre by 1.163e-6 to obtain the value in megawatts per square metre.

Worked example

Convert 1.00000e+6 kcal/(hr·m²) to MW/m².

  1. 01Start with 1.00000e+6 kcal/(hr·m²).
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1.163e-6 = 1.163 MW/m².
Result1.00000e+6 kcal/(hr·m²) = 1.163 MW/m²

FAQ

What is the conversion factor from kcal/(hr·m²) to MW/m²?
1 kcal/(hr·m²) equals 1.163e-6 MW/m². To convert, multiply the value in kilocalories per hour-square metre by 1.163e-6.
How do I convert 1 kcal/(hr·m²) to MW/m²?
1 kcal/(hr·m²) = 1.163e-6 MW/m². For any value, multiply by 1.163e-6.
How do I convert MW/m² back to kcal/(hr·m²)?
Divide by the same factor — or equivalently, multiply by 859845.2. So 1 MW/m² = 859845 kcal/(hr·m²).
When would I need to convert kilocalorie per hour-square metre to megawatt per square metre?
Heat-flux conversions between kcal/(hr·m²) and MW/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).
