1 MB = 1024KB, or does it?

There are two possible definitions, which makes this quite confusing

  • 1,024,000 bytes: the “traditional” definition that was used, for instance, to describe the formatted capacity of floppy disks.
  • 1,000,000 bytes: the “standard” definition, recommended by the International System of Units (SI) and the IEC (International Electrotechnical Commission)

Convex uses the latter definition, where 1 MB equals 1000KB and also implements the corresponding unit (MiB) where 1 MiB equals 1024 KiB.
