Thermal resistance calculator

The thermal resistance $R$ of a material or a structure is typically defined as the ratio of the temperature difference ($\Delta T$) across the material or structure to the heat transfer rate ($Q$) through it. Mathematically, it can be expressed as:

Where:

• $R$ is the thermal resistance (in units of K/W),
• $\Delta T$ is the temperature difference (in units of Kelvin or Celsius, $K$ or $°C$),
• $Q$ is the heat transfer rate (in units of watts, $W$).

This formula represents the thermal resistance in a general context. However, in specific applications or systems, there might be different formulas or expressions used to calculate thermal resistance depending on the geometry, material properties, and boundary conditions.
