Use proper size units
Currently (disk) sizes are provided with e.g. "GB" units, which usually mean base 10 ("SI") numbers with 1GB being 1.000.000.000 bytes. Unfortunately the disk sizes provided are base 2 numbers, which should be referred to with binary units like "GiB" (1GiB being 1024³ bytes). This may be confusing and lead to wrong conclusions. Proposed solution: Change units to the base 2 units (e.g. "GiB"). As this might introduce inconsistencies or problems with other systems (e.g. the Hetzner website) alternatively a --si switch could be added so that sizes can explicitly be printed with base 10 numbers (which probably introduces new problems). On the other hand it would be nice if the website also would use proper units.
