the definition of bits and bytes is different from the decimal
numeric point of calculation. in the electronics world, bytes are
either on or off (i.e 1 or 0, thus 2 possibliliies). since the
results of using this standarrd is very close to that of the
decimal in numeric table, it is often prefer to use the 1x1,000
analysis to represent 1kb and 1x1,000,000 to represent the 1MB
etc.
you will get confused when you packed a 4.7GB data for burning to a
DVD media but find that the computer willask you for continual
burning to a second disc since 4.7GB far exceeds 5.0gigibytes!
4.7gigabytes is only about 4.33GB!
in short 1 kb = 2 ^ 10
1 GB = 2^20
not 1 kB = 1 x 1,000
not 1MB = 1 x 1,000,000
