In heat transfer analysis, thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure. It measures the rate of transfer of heat of a material from the hot end to the cold end. It has the SI derived unit of m /s. Thermal diffusivity is usually denoted by lowercase alpha (α), but a, h, κ (kappa), K, and D are also used. The formula is:
