In case of castP, I feel, the unit of the area and volume is in
angstrom. They have not mentioned it anywhere, Thus for confirmation,
you can better contact the people who made it.

"Joe Dundas, Zheng Ouyang, Jeffery Tseng, Andrew Binkowski, Yaron
Turpaz, and Jie Liang. 2006. CASTp: computed atas of surface
topography of proteins with structural and topographical mapping of
functionally annotated residues. Nucl. Acids Res., 34:W116-W118."

And when you say, showing the pocket with space-filled, if you mean,
you want the space of the cavity and not the residues making it, this
can be done using PASS software. This software gives the cavities as
filled beads, and does not give any information about which residues
or atoms make this cavity. when you give a pdb file as input, it gives
u two files as output, 1. <file>.probes.pdb - this have all the
cavities of the protein space filled and 2. <file>.asps.pdb - this
file will have the coordinate of the centre of the each cavity
mentioned in the probes.pdb file. you can view these two files with
any standard molecule viewer along with the input file to understand
it better.

Hope this would help you. You can get back to me, in case you need more help.
