In 2005, there was a new standard introduced. Since some hardware manufacturers used 1000 MB = 1 GB and some used 1024 (or 2 to the 10th power) MB = 1 GB, there are now 2 systems: SI and IEC.
Now 1000 kilobytes is a megabyte, 1000 megabytes is a gigabyte, and so on. This is how all SI (metric) measurements are done, such as kilometer, kilogram, and such.
For computers, they made the IEC standard. Instead of kilobyte, it's kibibyte. Instead of megabyte, it's mebibyte. So 1024 bytes = 1 kibibyte, 1024 kibibytes = 1 mebibyte, and so on.
This is why when you buy an 80 GB hard drive, your computer only reports it as about 75. The hard drive manufacturer measured it in gigabytes, while your computer measures it in gibibytes.
byte, kibibyte, mebibyte, gibibyte, tebibyte...
The abbreviations just add a lowercase "i" between the letters, so Megabyte is abbreviated MB, Mebibyte is abbreviated MiB.
Hope that wasn't terribly confusing.

1 GB = 1024 MB . Be aware though that some hard disk manufacturers count it like 1 GB = 1000 MB . You computer will always count it using the first method though.
