Some popular binary conventions, include terms like kilo-, mega-, giga, etc. in normal language use imply base 10, such as 1000 or 10³. However, in the binary format for computers these terms have to be seen for a conversion factor of 1024 instead of 1000. To preclude confusions a few years ago the notation BI was introduced. Instead of kilobyte, kibibyte for kilo-binary-byte should be used.
In the class BINARY both notations can be found, such as
KILOBYTE = 1024 - binary
conputer conversion KIBIBYTE = 1024 - new notation KILO_BINARY_BYTE = 1024 - new,
or the notation, long format
KILOBYTE_SI = 1000 - SI notation for kilo (1000). DVDs for example are
marked with the SI-notation, but almost all harddisks are marked in computer binary
