The official definition of gigabyte (GB) is 1000 megabytes (MB).

The use of 1024 for memory is due to the use of binary addressing.

Computers were originally structured with memory based up 8 or 64. So any larger memory will be a multiple of this. First floppy drive was 512KB. Double this and you have 1024. Then this continued up to the Gigabyte sizes.

I know this is not a complete explanation but this is how the computer was made.
