1,073,741,824.

There are 1,073,741,824 bytes in a megabyte. Giga is a prefix that means ‘Ëœone billion’â„¢, so that roughly speaking a gigabyte should consist of one billion bytes. Because computer storage units are based on a binary numeral system based on the power of two, where one byte is equal to 23 bits, then it is more accurate to measure megabytes in terms of 230 or 1,073,741,824 bytes.
