Formula and example

How it is calculated

Converted value = original value × source factor / target factor

Worked example

2 K/W = 2 °C/W.

Things to check

  • The thermal resistance used here is measured in K/W. Area-specific thermal resistance in m²·K/W is a different quantity.
  • Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
