**Linear thermal expansion coefficient calculator** - formula & step by step calculation to find the object dimension change in one direction (length) opposed to change in volumetric expansion due to change of temperature. ΔL = αL x L x ΔT. Linear expansion coefficient αL in Kelvin, length L in meter & change of reference temperature ΔT in Kelvin are the key elements of this calculation. Density is the mass of any material per unit volume.

In mechanical engineering, the below mathematical formula is used to calculate the change of length of material due to change of temperature.

In the field of *mechanical engineering*, sometime, it's important to analyse the material characteristic changes due to temperature. The above formula & step by step calculation may useful for users to understand how the values are being used in the formula to find the change of length due to temperature, however, when it comes to online for quick calculations, this linear thermal expansion coefficient calculator helps the user to perform & verify such heat transfer calculations as quick as possible.
