How many megabytes are in a gigabyte

In computing, one gigabyte (GB) is specified to have a size of 10^9 bytes, or 1,073,741,824 bytes. This is based on 1000 megabytes (MB) per gigabyte (GB).As for megabyte, it is a multiple of the unit byte for digital information. As we can see, the unit prefix mega is a multiplier of 1,000,000 (106) in the International System of Units (SI). Therefore, megabyte is one million bytes of information. In other words, 1MB (the abbreviation MB stands for megabyte) is equal to 1,000,000 bytes.

Megabyte

In computer system, one megabyte equals to 1024 kilobytes. In other words, there are 1,048,576 bytes in 1 megabyte according to the binary system which computers use. So one gigabyte is equal to 1,073,741,824 bytes in base 2. This also means that there are 1,024 megabytes in one gigabyte in binary system. That's why you'll see kilobytes referred to as kibibytes and Megabytes as mibibytes in order to differentiate them. However, most people still use Megabytes to mean 1024 kiloBytes even if they really should say MibiBytes, and the same with GB and TB.

One megabyte is about 1 million bytes (or about 1000 kilobytes). An MP3 audio file of a few minutes or a 10 million pixel image from a digital camera would typically take up few megabytes. The rule of thumb for MP3 audio is that 1 minute of audio takes up about 1 megabyte. Audio and image and video data typically stored in "compressed" form, MP3 being an example. We'll talk about how compression works later. A data CD disk stores about 700 MB. The audio on a CD is not compressed, which is why it takes so much more space than the MP3. The series of bits are represented as spiral path of tiny pits in the silver material in the disk. Imagine that each pit is interpreted as a 0, and the lack of a pit is a 1 as the spiral sequence is read. Fun fact: the whole spiral on a CD is over 5km long.Current use: Megabytes are widely used in data storage for file sizes (documents, photos, videos, etc.) as well as for storage devices such as flash drives or, in the past, floppy disks. Today however, storage devices are typically larger, often involving either gigabytes (1000 (Source:www.unitconverters.net)
