Convert Watts per Square Metre Kelvin to kW/(m²·K)
1 watt per square metre kelvin (W/(m²·K)) = 0.001 kilowatts per square metre kelvin (kW/(m²·K)). 1 kW/(m²·K) = 1000 W/(m²·K). Example: 15 W/(m²·K) = 15 × 0.001 = 0.015 kW/(m²·K).

How to Convert Watt per Square Metre Kelvin to Kilowatt per Square Metre Kelvin
- 1 W/(m²·K) = 0.001 kW/(m²·K)
- 1 kW/(m²·K) = 1000 W/(m²·K)
- Example: convert 15 W/(m²·K) to kW/(m²·K): 15 W/(m²·K) = 15 × 0.001 kW/(m²·K) = 0.015 kW/(m²·K)
Formula
kW/(m²·K) = W/(m²·K) ÷ 1000
Derivation from SI units:
- The SI unit of heat transfer coefficient and thermal transmittance (U-value): heat flow (W) per square metre per kelvin
- 1 kW/(m²·K) = 1000 W/(m²·K)
Both units are defined exactly, so the factor is exact. Watt per Square Metre Kelvin definition: watt per square metre kelvin; Kilowatt per Square Metre Kelvin definition: kilowatt per square metre kelvin.
Worked examples
- A reading of 1.4 W/(m²·K) converts to 0.0014 kW/(m²·K).
1.4 W/(m²·K) × 0.001 = 0.0014 kW/(m²·K) - A value of 25 W/(m²·K) is 0.025 kW/(m²·K).
25 W/(m²·K) × 0.001 = 0.025 kW/(m²·K)

Where it's used
Watts per Square Metre Kelvin are used for building U-values (walls, roofs, windows), while kilowatts per square metre kelvin appear in shell-and-tube and plate heat exchangers. Both measure heat transfer coefficient (h) and thermal transmittance (U-value), so the conversion is a fixed factor.

Frequently asked questions
How many kilowatts per square metre kelvin are in 1 watt per square metre kelvin?
1 W/(m²·K) = 0.001 kW/(m²·K).
How do I convert watts per square metre kelvin to kilowatts per square metre kelvin?
Multiply the value in W/(m²·K) by 0.001, or divide it by 1000. For example, 15 W/(m²·K) × 0.001 = 0.015 kW/(m²·K).
Is the W/(m²·K) to kW/(m²·K) conversion exact?
Yes. Both units are defined exactly, and 1 W/(m²·K) is exactly 0.001 kW/(m²·K).
