Thermal Diffusivity Calculator

Thermal Diffusivity (α):

Thermal Conductivity (k):

Density (ρ):

Specific Heat Capacity (c):

How This Is Calculated

$$ \alpha = \frac{k}{\rho c} $$ where:

α = Thermal Diffusivity (m²/s)

k = Thermal Conductivity (W/mK)

ρ = Density (kg/m³)

c = Specific Heat Capacity (J/kg K)

Assumptions

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