kW/(m·K)tokcal/(hr·m·K)

Convert kilowatts per metre-kelvin (kW/(m·K)) to kilocalories per hour-metre-kelvin (kcal/(hr·m·K)).

Factor1 kW/(m·K) = 859.8452 kcal/(hr·m·K)

Converter

kW/(m·K)

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

Result
859.845kcal/(hr·m·K)

Rendered to 6 significant figures.

Formula

Formula
kcal/(hr·m·K) = kW/(m·K) × 859.8452

Multiply any value in kilowatts per metre-kelvin by 859.8452 to obtain the value in kilocalories per hour-metre-kelvin.

Worked example

Convert 1 kW/(m·K) to kcal/(hr·m·K).

  1. 01Start with 1 kW/(m·K).
  2. 02Multiply by the conversion factor: 1 × 859.8452 = 859.845 kcal/(hr·m·K).
Result1 kW/(m·K) = 859.845 kcal/(hr·m·K)

FAQ

What is the conversion factor from kW/(m·K) to kcal/(hr·m·K)?
1 kW/(m·K) equals 859.8452 kcal/(hr·m·K). To convert, multiply the value in kilowatts per metre-kelvin by 859.8452.
How do I convert 1 kW/(m·K) to kcal/(hr·m·K)?
1 kW/(m·K) = 859.845 kcal/(hr·m·K). For any value, multiply by 859.8452.
How do I convert kcal/(hr·m·K) back to kW/(m·K)?
Divide by the same factor — or equivalently, multiply by 0.001163. So 1 kcal/(hr·m·K) = 0.001163 kW/(m·K).
When would I need to convert kilowatt per metre-kelvin to kilocalorie per hour-metre-kelvin?
Thermal conductivity conversions between kW/(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).
