W/(m²·K)tokW/(m²·K)

Convert watts per square metre-kelvin (W/(m²·K)) to kilowatts per square metre-kelvin (kW/(m²·K)).

Factor1 W/(m²·K) = 0.001 kW/(m²·K)

Converter

W/(m²·K)

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

Result
1kW/(m²·K)

Rendered to 6 significant figures.

Formula

Formula
kW/(m²·K) = W/(m²·K) × 0.001

Multiply any value in watts per square metre-kelvin by 0.001 to obtain the value in kilowatts per square metre-kelvin.

Worked example

Convert 1000 W/(m²·K) to kW/(m²·K).

  1. 01Start with 1000 W/(m²·K).
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 kW/(m²·K).
Result1000 W/(m²·K) = 1 kW/(m²·K)

FAQ

What is the conversion factor from W/(m²·K) to kW/(m²·K)?
1 W/(m²·K) equals 0.001 kW/(m²·K). To convert, multiply the value in watts per square metre-kelvin by 0.001.
How do I convert 1 W/(m²·K) to kW/(m²·K)?
1 W/(m²·K) = 0.001 kW/(m²·K). For any value, multiply by 0.001.
How do I convert kW/(m²·K) back to W/(m²·K)?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kW/(m²·K) = 1000 W/(m²·K).
When would I need to convert watt per square metre-kelvin to kilowatt per square metre-kelvin?
Heat-transfer coefficient conversions between W/(m²·K) and kW/(m²·K) 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).
