A KB is 1024 bytes. A GB is 1024 KB, that is, 1024*1024 (or 1024^2) bytes. A MB is 1024 MB, or 1024^3 KB. Look for the definitions in www.pcwebopedia.com, or in www.whatis.com.

Hard-disk manufacturers usually use KB as 1000, MB as 1000^2, and GB 1000^3, for the same reasons that screens size is indicated with the diagonal, and alcoholic beverages indicate the percentage as percent-volumen (instead of percent-weight). In the case of hard-disks, even serious publications erroneously state that the "formatted capacity" is so-and-so much. The difference is not due to "formatting" but to the different definitions used for GB, etc.

Met hartelijke groeten,

Hilmar.
