# Thermal Resistance Calculator

## Overview  This calculates a measurement of a temperature difference between two materials and their ability to resist the flow of heat. Rwall = Thermal resistance for conductive heat transfer through a plane wall (K/W) x = Thickness of a plane wall  k = Average thermal conductivity  A = Heat transfer area

Inputs
Material
Width
Length
Thickness

Output
Thermal resistance
°C/W

### Equations

To calculate for a plane wall:

$$Rwall = x/kA$$

### Application

Knowing the thermal resistance between two components of a device will calculate for temperature differences.
