Kilobytes vs kibibytes
Storage makers count in powers of ten: 1 KB is 1,000 bytes and 1 GB is a billion bytes. Operating systems often count in powers of two, where 1 KiB is 1,024 bytes and 1 GiB is 1,073,741,824 bytes. That gap is why a 1 TB drive shows up as roughly 931 GB in your file manager — both numbers are correct, they just use different units.
