Thermal Expansion Calculator

Change in length (Δ L):

Original Length (L₀):

Thermal Expansion Coefficient (α):

Change in temperature (Δ T):

How This Is Calculated

$$ \Delta L = L_0 \cdot \alpha \cdot \Delta T $$ where:

Δ L = Change in length (m)

L₀ = Original Length (m)

α = Thermal Expansion Coefficient (K^-1)

Δ T = Change in temperature (K)

Assumptions

The material properties are constant.
There is no internal heat generation.
Material is homogeneous.
The material is isotropic.
