How many bytes are there in a megabyte or gigabyte?
There has been long standing debate about prefixes for multiples of bytes. We have chosen to utilize the standard supported by the International System of Units (SI) where 1 gigabyte (GB) = 109 bytes or 1 megabyte (MB) = 106 bytes. This convention is also supported by the IEEE, EU, NIST, and the International System of Quantities. Where appropriate, we utilize the IEEE 1541 recommendations for binary representation where 10243 bytes = 1 gibibyte (GiB) or 10242 bytes = 1 mebibyte (MiB).
