UDS-diffusivity coefficient
hello everybody! I'm trying to use a UDS model to describe the diffusion of species dissolved in a solution. I got the diffusivity coefficients I need in m^2/s but I can't understand whether using m^2/s as units for diffusivity is right, while next to the box in the drop-down list in materials properties the units are kg/m-s like viscosity. I thought I have to convert the diffusivity value in m^2/s, as Fickian diffusivity value for my species, to these units but it's a kind of freakingly strange thing I hope you can help me and i thank you as well!
