I believe for computer uses there are 1024 Kilobytes in a Megabyte. I am not sure why it is not 1000, like it is for everything else.

Computers are on the base 8 counting method in other words multiples of 8. 8 x 128 = 1024

Because of the binary system.

Decimal : 0, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024

each time you carry, you double... sort of but not quite.

Its very hard to explain without drawing tables on scraps of paper and listing numbers, and its hard to understand unless you have an interest in advanced electronics/microprocessor sytsems, trust me on that, its because of the fundamental way computers operate...or..."coz it is." ;)


Here is a quick chart, Dan

Pocket Ref, 2nd ed. by Thomas J. Glover shows (using lower case though):

1 kilobyte = 2 to the 10th bytes = exactly 1,024 bytes
1 megabyte = 2 to the 20th bytes = exactly 1,048,576 bytes
1 gigabyte = 2 to the 30th bytes = exactly 1,073,741,284 bytes
1 terabyte = 2 to the 40th bytes = exactly 1,099,511,627,776 bytes
1 petabyte = 2 to the 50th bytes = exactly 1,125,899,906,842,6204 bytes
