When talking about digital data storage K means times 2^10, M means 
times 2^20, G means 2^30 and T means 2^40.

1K = 1 * 2^10 bytes = 1024 bytes
1M = 1 * 2^20 bytes = 1048576 bytes
1G = 1 * 2^30 bytes = 1073741824 bytes

If you think otherwise go google "what is a megabyte". Didn't you ever 
wonder why your computer with 512 megabytes of ram always showed 
536870912 bytes? Or even hop on a FreeBSD box and do a:

dd if=/dev/random of=bigfile bs=1 count=1M

Watch as it reports "1048676 blocks in/out".
