Thermal diffusivity has the SI derived unit of, and is usually denoted α but a, κ, K, and D are also used. It can be calculated by taking the thermal conductivity divided by density and specific heat capacity at constant pressure. Thermal diffusivity is the rate of transfer of heat of a material from the hot side to the cold side - a measure of how quickly a material can absorb heat from its surroundings.
