Factor1 W/cm² = 10000 W/m²

Converter

W/cm²

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

Result
10000W/m²

Rendered to 6 significant figures.

Formula

Formula
W/m² = W/cm² × 10000

Multiply any value in watts per square centimetre by 10000 to obtain the value in watts per square metre.

Worked example

Convert 1 W/cm² to W/m².

  1. 01Start with 1 W/cm².
  2. 02Multiply by the conversion factor: 1 × 10000 = 10000 W/m².
Result1 W/cm² = 10000 W/m²

FAQ

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