The difference between megabytes and gigabytes is the number of bytes that make up each unit and the amount of data they hold. A megabyte holds a million bytes, or about 1,000 kilobytes. A gigabyte holds about a billion bytes, or around 1,000 megabytes. Continue Reading.
In terms of data, one MB is 1,000 times larger than one KB. A kilobyte is 1,000 bytes, while one MB, which stands for megabyte, comprises 1 million bytes. Continue Reading. The way MB and KB are capitalized makes a big difference in what is being discussed. When talking about data transfer speeds, one is discussing megabits and kilobits, not megabytes and kilobytes. Bits are abbreviated as mb or kb, while bytes, which measure size, are abbreviated as MB or KB, respectively. The progression in units of data measurements is bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes, zettabytes and finally, yottabytes. Each one is 1,000 times larger than the previous.
