Usando essa notação, para o metro (''m'') teremos, de interesse geográfico: | |||
* '''1 Kim''' (um ''kibi'' metro - ''Ki'' é o análogo do ''k'' de ''quilo'') = 1024 m. O "kibi" é abreviação de "kilobinary". | |||
* '''1 Mim''' (um ''mebi'' metro - ''Mi'' é o análogo do ''M'' de ''Mega'') = 1024<sup>2</sup> m. O "mebi" é abreviação de "megabinary". | |||
