Decimal (SI): 1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes (used by storage manufacturers)
Binary (IEC): 1 KiB = 1,024 bytes, 1 MiB = 1,048,576 bytes (used by operating systems)
Byte Converter - 技术详情
Storage manufacturers use decimal units (1 KB = 1,000 bytes) while operating systems use binary units (1 KiB = 1,024 bytes). This is why a '500 GB' drive shows as ~465 GiB in your OS. The IEC introduced KiB, MiB, GiB to distinguish binary units.
