kW/m²toMW/m²

Convert kilowatts per square metre (kW/m²) to megawatts per square metre (MW/m²).

Factor1 kW/m² = 0.001 MW/m²

Converter

kW/m²

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

Result
1MW/m²

Rendered to 6 significant figures.

Formula

Formula
MW/m² = kW/m² × 0.001

Multiply any value in kilowatts per square metre by 0.001 to obtain the value in megawatts per square metre.

Worked example

Convert 1000 kW/m² to MW/m².

  1. 01Start with 1000 kW/m².
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 MW/m².
Result1000 kW/m² = 1 MW/m²

FAQ

What is the conversion factor from kW/m² to MW/m²?
1 kW/m² equals 0.001 MW/m². To convert, multiply the value in kilowatts per square metre by 0.001.
How do I convert 1 kW/m² to MW/m²?
1 kW/m² = 0.001 MW/m². For any value, multiply by 0.001.
How do I convert MW/m² back to kW/m²?
Divide by the same factor — or equivalently, multiply by 1000. So 1 MW/m² = 1000 kW/m².
When would I need to convert kilowatt per square metre to megawatt per square metre?
Heat-flux conversions between kW/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).
