Digital storage converter
A kilobyte is 1000 bytes; a kibibyte is 1024. Drive makers use the first, operating systems often show the second, and that gap is why a "1 TB" drive reports 931 GB.

About digital storage units
Convert bytes, kilobytes, kibibytes, megabytes, gigabytes and terabytes — decimal and binary kept distinct.
A kilobyte is 1000 bytes; a kibibyte is 1024. Drive makers use the first, operating systems often show the second, and that gap is why a "1 TB" drive reports 931 GB.
Dimensional formula: 1. Every conversion on this page goes through the bit, using exact fractions rather than decimal approximations. Read how that works →
