How many bytes in a gb

Therefore, a byte , or eight bits, is used as the fundamental unit of measurement for data storage. A byte can store different values, which is sufficient to represent standard ASCII table, such as all numbers, letters and control symbols.

Since most files contain thousands of bytes, file sizes are often measured in kilobytes. Larger files, such as images, videos, and audio files, contain millions of bytes and therefore are measured in megabytes.

Modern storage devices can store thousands of these files, which is why storage capacity is typically measured in gigabytes or even terabytes. The gigabyte is a multiple of the unit byte for digital information. A zettabyte is 1,,,,,,, 2 70 bytes, 1, exabytes, 1,, petabytes, 1,,, terabytes, 1,,,, gigabytes, or 1,,,,, megabytes.

A yottabyte is 1,,,,,,,, 2 80 bytes, 1, zettabytes, 1,, exabytes, 1,,, petabytes, 1,,,, terabytes, 1,,,,, gigabytes, or 1,,,,,, megabytes.

As of , there are no approved standard sizes for anything bigger than a yottabyte. However, the two proposed standards are hellabyte or brontobyte. Calculating the above values is simple once you know the values of each of the above sizes.

For example, in the gigabyte section above, we know that 1 gigabyte is equal to 1, megabytes. You can also use our search engine to search engine and our conversion tool also to convert and compare between values.

Home Help Computer Storage. How much is 1 byte, kilobyte, megabyte, gigabyte, etc.? Tip Except for a bit and a nibble, all values explained below are in bytes and not bits. Connect and share knowledge within a single location that is structured and easy to search. When I convert between 1GB to byte using online tools, I get different answers.

How can I know which unit my machine uses using a small C program or function? Does C have a macro for that? I want to do that as my program will possibly be run via various operating systems. The two tools are converting two different units. Try using google converter with GiB instead of GB and the mystery will be solved.

Note that the new prefixes for binary multiples are not part of the International System of Units SI. However, for ease of understanding and recall, they were derived from the SI prefixes for positive powers of ten.

As shown in the table, the name of each new prefix is derived from the name of the corresponding SI prefix by retaining the first two letters of the SI prefix and adding the letters bi. Think about the hard drives world: Your operating system assumes that 1 MB equals 1 bytes i.

Drive manufacturers consider correctly 1 MB as equal to 1 bytes. Thus if the drive is advertised as 6. Take a look at this for more info on prefixes for binary units and this on metric prefixes. This is just a confusion of units. Bytes should usually be measured with the second, so the correct writing would be GiB. The unit symbol for the gibibyte is GiB.
