Gigabytes to Gibibytes converter
Quick reference
About digital storage units
Digital storage has two competing systems that look alike: decimal units (kilobyte = 1,000 bytes) used by drive manufacturers, and binary units (kibibyte = 1,024 bytes) used by operating systems for memory. That gap is why a "1 TB" drive shows up as roughly 931 GiB in Windows: both numbers are right, they just use different definitions. This converter handles both families, so you can translate marketing gigabytes into the gibibytes your OS reports.
