Describe the bug
The displayed unit in the webinterface for drive capacity is wrong. It displays base 1000 units (GB) although the calculated size is base 1024.
It's the same issue with Windows, which also calculates with base 1042, but uses base 1000 units.
So, scrutiny calculates with base 1024, but does not use base 1042 units, which should be f.ex. Gibibyte (GiB).

Expected behavior
Either

a) calculate with base 1000 and display base 1000 (500 GB)
b) calculate with base 1024 and display base 1024 (465 GiB)

Preferably, let the user decide in the settings.

Screenshots

Same in Windows:

smartctl reports the capacity correctly
