How does this file size converter work?

This tool helps you convert file storage sizes from one unit of measurement to another. You just choose the unit to begin with and then input the numerical value.

File sizes are usually measured in bytes with a prefix. These also relate to the amount of disk space that a file can consume which is no more than the bits the computer file system can support.

Example of a result

A file with a size of 123 megabytes is equal to:

1031798784

bits

128,974,848

bytes

125,952

kilobytes

123

megabytes

0.120117188

gigabytes

0.000117302

terabytes

1.146E-07

petabytes

The basic unit used for computer data storage is the bit, binary digit, composed by ones and zeros. All files are kept in the system as binary files and translated into words, images etc. by the software. A byte is a sequence of 8 bits.

For example, one alphanumeric character uses one byte of memory. A kilobyte represents 1024 bytes in the binary system and 1000 bytes in the decimal system. A megabyte is 1024 kilobytes and so on. Although computer data is practically measured in binary system so 1 KB is made of 1024 bytes, for simplicity the decimal system was added so 1kB is made of approximately 1000 bytes.

Where do you find the file size? 

These can be found easily in any operating system. In Windows, the properties section in each file will show the size in the most appropriate unit for the life size.

In Mac OS X you can press Command+i to show details of a particular file, including file size. Most email programs also show the size of the attachments next to the file specifications. All FTP programs also show by default the sizes of the files transferred to websites.
