About these units

The byte (B) is a specialist or regional unit of data storage.

The bit (b) is a specialist or regional unit of data storage, equal to 0.125 bytes.

Going the other way, 1 bit = 0.125 bytes. Storage has two competing definitions: drive makers count a gigabyte as 1,000,000,000 bytes, while operating systems often show gibibytes of 1,073,741,824 bytes. That 7% gap is why a '1 TB' drive shows up as 931 GB. Both families are included below so you can compare them directly.
