W/(cm·K)tomW/(m·K)

Convert watts per centimetre-kelvin (W/(cm·K)) to milliwatts per metre-kelvin (mW/(m·K)).

Factor1 W/(cm·K) = 100000 mW/(m·K)

Converter

W/(cm·K)

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

Result
100000mW/(m·K)

Rendered to 6 significant figures.

Formula

Formula
mW/(m·K) = W/(cm·K) × 100000

Multiply any value in watts per centimetre-kelvin by 100000 to obtain the value in milliwatts per metre-kelvin.

Worked example

Convert 1 W/(cm·K) to mW/(m·K).

  1. 01Start with 1 W/(cm·K).
  2. 02Multiply by the conversion factor: 1 × 100000 = 100000 mW/(m·K).
Result1 W/(cm·K) = 100000 mW/(m·K)

FAQ

What is the conversion factor from W/(cm·K) to mW/(m·K)?
1 W/(cm·K) equals 100000 mW/(m·K). To convert, multiply the value in watts per centimetre-kelvin by 100000.
How do I convert 1 W/(cm·K) to mW/(m·K)?
1 W/(cm·K) = 100000 mW/(m·K). For any value, multiply by 100000.
How do I convert mW/(m·K) back to W/(cm·K)?
Divide by the same factor — or equivalently, multiply by 1e-5. So 1 mW/(m·K) = 1e-5 W/(cm·K).
When would I need to convert watt per centimetre-kelvin to milliwatt per metre-kelvin?
Thermal conductivity conversions between W/(cm·K) and mW/(m·K) are common in insulation specification, heat-exchanger design, and building-envelope analysis. SI units (W/(m·K)) appear in international standards and simulation tools, while BTU/(hr·ft·°F) is standard in US codes and vendor 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).
