SI multiples. For example, a channel capacity may be specified as 8 kbit/s = 1 kB/s.

Storage

File sizes are often measured in (binary) IEC multiples of bytes, for example, 1 KiB = 1024 bytes = 8192 bits. Confusion may arise in cases where (for historic reasons) file sizes are specified with binary multipliers using the ambiguous prefixes K, M, and G rather than the IEC standard prefixes Ki, Mi, and Gi.

Mass storage devices are usually measured in decimal SI
