# How many megabytes in a gigabyte?

Gigabyte - one of the units of information measurementalong with bytes, kilobytes and megabytes. About what a megabyte is and what it is equal to, we told in our previous article What does mb mean, and this time we'll talk about how many megabytes in gigabyte.

## How many megabytes in gigabyte

The minimum unit of information is byte, so all the others, larger ones, are calculated above all relative to it. One gigabyte is 230byte, or 1073741824 bytes, but remember this,of course, difficult, and it is unlikely that this accuracy is relevant for a simple user. It's easier to understand how many megabytes are in 1 gigabyte - and there are 1024 of them, just like in 1 megabyte - 1024 kilobytes, and in one kilobyte - 1024 bytes.

But it is worth noting that this is not the onlythe value of gigabytes. To consider that in 1 gigabyte 1024 megabytes, it is accepted first of all in the sphere of computer technologies, where the calculus occurs in the binary system. Such rules are prescribed in the JEDEC standard.

But in the International system of units, where the decimal number system is applied, 1 gigabyte is equal to 109bytes, that is 1000000000 bytes, or 1000 megabytes. However, if gigabytes only interest you with respect to the size of files on the Internet and on a computer, you can not go into such subtleties and consider that in 1 gigabyte - 1024 megabytes.
