W/m²toW/cm²

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

Factor1 W/m² = 0.0001 W/cm²

Converter

W/m²

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

Result
1W/cm²

Rendered to 6 significant figures.

Formula

Formula
W/cm² = W/m² × 0.0001

Multiply any value in watts per square metre by 0.0001 to obtain the value in watts per square centimetre.

Worked example

Convert 10000 W/m² to W/cm².

  1. 01Start with 10000 W/m².
  2. 02Multiply by the conversion factor: 10000 × 0.0001 = 1 W/cm².
Result10000 W/m² = 1 W/cm²

FAQ

What is the conversion factor from W/m² to W/cm²?
1 W/m² equals 0.0001 W/cm². To convert, multiply the value in watts per square metre by 0.0001.
How do I convert 1 W/m² to W/cm²?
1 W/m² = 0.0001 W/cm². For any value, multiply by 0.0001.
How do I convert W/cm² back to W/m²?
Divide by the same factor — or equivalently, multiply by 10000. So 1 W/cm² = 10000 W/m².
When would I need to convert watt per square metre to watt per square centimetre?
Heat-flux conversions between W/m² and W/cm² 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).
