 Na [[wikipedia:Binary prefix]]
-: ''is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two. The most commonly used binary prefixes are kibi (symbol '''Ki''', meaning 210= 1024), mebi ('''Mi''', 220 = 1048576), and gibi ('''Gi''', 230 = 1073741824). They are most often used in information technology as multipliers of bit and byte, when expressing the capacity of storage devices or the size of computer files''

-: (...) ''the binary prefixes "kibi", "mebi", etc. were defined in 1999 by the International Electrotechnical Commission (IEC), in the IEC 60027-2 standard (Amendment 2). They were meant to replace the metric (SI) decimal power prefixes, such as "kilo" ("k", 103 = 1000), "mega" ("M", 106 = 1000000) and "giga" ("G", 109 = 1000000000)''

 Usando essa notação, para o metro (m) teremos:
 * 1 Kim (''one kibi meter'') = 1024 m
 * 1 Mim (''one mebi meter'') = 1024<sup>2</sup> m
