Diffusivity is a rate of diffusion, a measure of the rate at which particles or heat or fluids can spread.

It is measured differently for different mediums.

Diffusivity may refer to:

Thermal diffusivity, diffusivity of heat

Diffusivity of mass:

Mass diffusivity, molecular diffusivity (often called "diffusion coefficient")

Eddy diffusion, eddy diffusivity

Viscosity#Kinematic_viscosity, momentum diffusivity

Magnetic diffusivity
