A gigabyte contains 1,048,576 kilobytes. Some manufacturers and developers that do not use binary base 2 consider a GB to contain 1,000,000 KB. GB and KB indicate the amount of disk space or storage space in computers and other electronic devices.
The smallest measurement of storage is a bit. It contains 1 binary digit, which is either 1 or 0. Eight bits equal 1 byte, and 1024 bytes make 1 KB. There are 1024 KB in a megabyte and 1024 MB in a GB. Larger terms of storage measurement include the terabyte, petabyte, exabyte, zettabyte and yottabyte.
Users of technology find it helpful to understand these measurements of storage to determine how much disk space a file occupies on their hard drives and how much space is left before additional storage space is necessary. Devices with larger amounts of storage space cost more money and are present in newer versions of technology.
GB is the most common measurement of disk space and drive storage. Two CD-ROMs equal approximately 1 GB. One hundred GB can hold an entire floor of library information.
As technology advances, the TB will replace the GB as the most common measurement of disk space, allowing users additional storage on smaller devices.
