Conversion examples (rounded)

  • 1 W/(m²·K) = 0.001 kW/(m²·K)
  • 10 W/(m²·K) = 0.01 kW/(m²·K)

Some supported units: W/(m²·K) · kW/(m²·K) · W/(cm²·K) · BTU/(h·ft²·°F) (4 units in this category).

How do you convert W/(cm²·K) to W/(m²·K)?

Since 1 m² contains 10,000 cm², multiply the value in W/(cm²·K) by 10,000.

  • 1 W/(cm²·K) = 10,000 W/(m²·K)
  • 1 kW/(m²·K) = 1,000 W/(m²·K)
Are K and °C equivalent for temperature differences?

A temperature difference of 1 K has the same size as 1 °C; absolute temperature values differ. Heat-transfer coefficient also differs from thermal conductivity in W/(m·K).
