Is 1 gig equal to 512MB?

Question

my little brother says that 512MB is only half of a gig. but i think that its a whole gig. just trying to settle a little argument.

Answer 1

1 gigabyte= 1000 megabytes. Don't they teach kids the Roman pre-fixes anymore?

Answer 2

It's half. sorry.

1024mb is 1gb

when using binary (which is most common i.e - 128, 256, 512, 1024) 1024 is the magic number when referring to bits and bytes.

1024 bytes = 1kb (kilobyte)

1024 KB = 1mb (megabyte)

1024 MB = 1GB (gigabyte)

1024 GB = 1TB (terabyte)

when using decimal it is a round 1000.

Answer 3

1 gig = 1,024 MB

sorry, but you lose.  

Answer 4

No, one gigabyte is not equal to 512 megs, it is a little more than half of a gig:

1kb = 1000 bytes

1mb = 100 k.bytes

1gb = 1000 mb

1tb = 100gb
