About megabyte and gigabyte
Megabyte: A megabyte is 1,000,000 bytes (decimal). The binary 1,048,576-byte unit is the mebibyte (MiB).
Gigabyte: A gigabyte is 1,000,000,000 bytes (decimal). The binary unit is the gibibyte (GiB) = 1,073,741,824 bytes.
This converter uses the decimal (SI) convention for KB/MB/GB/TB (1 KB = 1,000 bytes), as used by storage manufacturers and networks. The binary units — KiB, MiB, GiB (1 KiB = 1,024 bytes) — are listed separately, because operating systems often label binary sizes with the decimal names.
