W/cm²toMW/m²

Convert watts per square centimetre (W/cm²) to megawatts per square metre (MW/m²).

Factor1 W/cm² = 0.01 MW/m²

Converter

W/cm²

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

Result
1MW/m²

Rendered to 6 significant figures.

Formula

Formula
MW/m² = W/cm² × 0.01

Multiply any value in watts per square centimetre by 0.01 to obtain the value in megawatts per square metre.

Worked example

Convert 100 W/cm² to MW/m².

  1. 01Start with 100 W/cm².
  2. 02Multiply by the conversion factor: 100 × 0.01 = 1 MW/m².
Result100 W/cm² = 1 MW/m²

FAQ

What is the conversion factor from W/cm² to MW/m²?
1 W/cm² equals 0.01 MW/m². To convert, multiply the value in watts per square centimetre by 0.01.
How do I convert 1 W/cm² to MW/m²?
1 W/cm² = 0.01 MW/m². For any value, multiply by 0.01.
How do I convert MW/m² back to W/cm²?
Divide by the same factor — or equivalently, multiply by 100. So 1 MW/m² = 100 W/cm².
When would I need to convert watt per square centimetre to megawatt per square metre?
Heat-flux conversions between W/cm² 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).
