Factor1 mW/(m·K) = 0.0008598452 kcal/(hr·m·K)

Converter

mW/(m·K)

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

Result
0.859845kcal/(hr·m·K)

Rendered to 6 significant figures.

Formula

Formula
kcal/(hr·m·K) = mW/(m·K) × 0.0008598452

Multiply any value in milliwatts per metre-kelvin by 0.0008598452 to obtain the value in kilocalories per hour-metre-kelvin.

Worked example

Convert 1000 mW/(m·K) to kcal/(hr·m·K).

  1. 01Start with 1000 mW/(m·K).
  2. 02Multiply by the conversion factor: 1000 × 0.0008598452 = 0.859845 kcal/(hr·m·K).
Result1000 mW/(m·K) = 0.859845 kcal/(hr·m·K)

FAQ

What is the conversion factor from mW/(m·K) to kcal/(hr·m·K)?
1 mW/(m·K) equals 0.0008598452 kcal/(hr·m·K). To convert, multiply the value in milliwatts per metre-kelvin by 0.0008598452.
How do I convert 1 mW/(m·K) to kcal/(hr·m·K)?
1 mW/(m·K) = 0.000859845 kcal/(hr·m·K). For any value, multiply by 0.0008598452.
How do I convert kcal/(hr·m·K) back to mW/(m·K)?
Divide by the same factor — or equivalently, multiply by 1163. So 1 kcal/(hr·m·K) = 1163 mW/(m·K).
When would I need to convert milliwatt per metre-kelvin to kilocalorie per hour-metre-kelvin?
Thermal conductivity conversions between mW/(m·K) and kcal/(hr·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).
