Is 1GB equal to 1024 MB or 1000 MB?

Currently the standard is 1 Gigabyte (GB) = 1000 Megabytes (MB). But it wasn’t always like that. For a long time, 1 Kilobyte=1024 bytes, 1 Megabyte = 1024 kilobytes, 1 Gigabyte = 1024 megabytes, and so on. The reason being the fact that it easier to do binary math when working with powers of two.

How much exactly is 1 GB?
