Definition: unit prefix used to form a multiple of a unit obtained by multiplying this unit by a power of two

NOTE – SI prefixes refer strictly to powers of 10 and should not be used for power of 2. For example, 1 kilobit should not be used to represent 1 024 bits ((210 bits) bits), which is 1 kibibit.
