kW/(m²·K)tokcal/(hr·m²·°C)

Convert kilowatts per square metre-kelvin (kW/(m²·K)) to kilocalories per hour-square metre-Celsius (kcal/(hr·m²·°C)).

Factor1 kW/(m²·K) = 859.8452 kcal/(hr·m²·°C)

Converter

kW/(m²·K)

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

Result
859.845kcal/(hr·m²·°C)

Rendered to 6 significant figures.

Formula

Formula
kcal/(hr·m²·°C) = kW/(m²·K) × 859.8452

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

Worked example

Convert 1 kW/(m²·K) to kcal/(hr·m²·°C).

  1. 01Start with 1 kW/(m²·K).
  2. 02Multiply by the conversion factor: 1 × 859.8452 = 859.845 kcal/(hr·m²·°C).
Result1 kW/(m²·K) = 859.845 kcal/(hr·m²·°C)

FAQ

What is the conversion factor from kW/(m²·K) to kcal/(hr·m²·°C)?
1 kW/(m²·K) equals 859.8452 kcal/(hr·m²·°C). To convert, multiply the value in kilowatts per square metre-kelvin by 859.8452.
How do I convert 1 kW/(m²·K) to kcal/(hr·m²·°C)?
1 kW/(m²·K) = 859.845 kcal/(hr·m²·°C). For any value, multiply by 859.8452.
How do I convert kcal/(hr·m²·°C) back to kW/(m²·K)?
Divide by the same factor — or equivalently, multiply by 0.001163. So 1 kcal/(hr·m²·°C) = 0.001163 kW/(m²·K).
When would I need to convert kilowatt per square metre-kelvin to kilocalorie per hour-square metre-Celsius?
Heat-transfer coefficient conversions between kW/(m²·K) and kcal/(hr·m²·°C) are needed in heat-exchanger sizing, boiler and condenser design, and HVAC calculations. W/(m²·K) is standard in SI engineering, and BTU/(hr·ft²·°F) is common in US heat-exchanger correlations and vendor literature.
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).
