SUMMARY
The discussion focuses on calculating thermal resistance for convection using the formula R = 1/hA, where R represents thermal resistance, h is the convective heat transfer coefficient, and A is the area. When the area is unknown, participants suggest assuming a width of 1 meter to derive a resistance per unit area, resulting in a value of 1/4 ohm per square meter. If a specific area, such as 1/2 m², is provided, the resistance can be calculated directly or adjusted accordingly, yielding a resistance of 1/8 ohm. The thickness of the material is clarified to be equivalent to h in the equation.
