mW/(m·K)toW/(cm·K)

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

Factor1 mW/(m·K) = 1e-5 W/(cm·K)

Converter

mW/(m·K)

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

Result
1W/(cm·K)

Rendered to 6 significant figures.

Formula

Formula
W/(cm·K) = mW/(m·K) × 1e-5

Multiply any value in milliwatts per metre-kelvin by 1e-5 to obtain the value in watts per centimetre-kelvin.

Worked example

Convert 100000 mW/(m·K) to W/(cm·K).

  1. 01Start with 100000 mW/(m·K).
  2. 02Multiply by the conversion factor: 100000 × 1e-5 = 1 W/(cm·K).
Result100000 mW/(m·K) = 1 W/(cm·K)

FAQ

What is the conversion factor from mW/(m·K) to W/(cm·K)?
1 mW/(m·K) equals 1e-5 W/(cm·K). To convert, multiply the value in milliwatts per metre-kelvin by 1e-5.
How do I convert 1 mW/(m·K) to W/(cm·K)?
1 mW/(m·K) = 1e-5 W/(cm·K). For any value, multiply by 1e-5.
How do I convert W/(cm·K) back to mW/(m·K)?
Divide by the same factor — or equivalently, multiply by 100000. So 1 W/(cm·K) = 100000 mW/(m·K).
When would I need to convert milliwatt per metre-kelvin to watt per centimetre-kelvin?
Thermal conductivity conversions between mW/(m·K) and W/(cm·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).
