How to Convert Resistance to Temperature

Resistance is the electrical property of a material that opposes the flow of electricity through it. This degree of resistance to electricity is defined by another property of the material called Resistivity.
The resistivity of a material is defined as the resistance to current flow between the opposite faces of a unit cube of the material (ohm per unit length). Hence the resistance R of a component is expressed by:

R = ρL/A

Where:
R = Resistance of the component in Ohms
L = Length of the component
A = Cross sectional Area of the component
ρ = Resistivity of the material
To use the above formula, L and A must be in compatible units
