Digital storage / decimal and binary
Digital Storage Converter
Convert bits, bytes, kilobytes, megabytes, gigabytes, terabytes, kibibytes, mebibytes, gibibytes, and tebibytes. 1 byte = 8 bits. Decimal SI units: 1 kB = 1000 B, 1 MB = 1,000,000 B, 1 GB = 1,000,000,000 B, 1 TB = 1,000,000,000,000 B. Binary IEC units: 1 KiB = 1024 B, 1 MiB = 1024² B, 1 GiB = 1024³ B, 1 TiB = 1024⁴ B. Bytes are the internal base. MB is not Mb. GB is not GiB.
Decimal: kB, MB, GB, TB use 1000.
Binary: KiB, MiB, GiB, TiB use 1024.

Why drive labels disagree
A manufacturer may advertise 1 GB as 1,000,000,000 bytes while an operating system reports gibibytes. 1 GB is about 0.931 GiB. That difference is a unit convention, not missing hardware. File-system overhead is a separate issue and is not part of this conversion.
