Size of files in Windows OS. (It's KB or kB?) One kilobyte (KB) is 1024 bytes in JEDEC-standard, whereas the definition has shifted, in most contexts, to mean 1000 bytes (kB) in accordance with SI.

an MB, which typically stands for Megabyte is larger than a KB, which typically stands for Kilobyte. These are metric names, signifying 1 Million bytes and 1 Thousand bytes respectively. Be careful, however, as most internet connections are based on MegaBits (or kilobits) and not Megabyte.
