Formula and example

How it is calculated

Converted value = original value × source factor / target factor

Worked example

1.2 W/(m²·K) = 0.0012 kW/(m²·K).

Things to check

  • The coefficient expresses heat flow per area and temperature difference. Conduction through a material and heat transfer at a surface use different models.
  • Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
