Multiples of bits
The mebibit is closely related to the megabit which equals 106 bits = 1,000,000 bits.
Throughout the 1980s and 1990s, video game manufacturers would sometimes report the amount of internal cartridge ROM (in megabits) on their packaging. 1 megabit equaled 128 kibibyte; 8 megabits were 1 mebibyte of ROM containing game instructions and data.
The binary prefixes are not part of the International System of Units (SI).
