Frequently asked questions

Using binary units, 1 gigabyte equals 1024 megabytes, and 1 megabyte equals 1024 kilobytes.

This converter uses the traditional binary system where each step is 1024. Some storage makers use 1000-based units, so a marketed 1 TB drive can show as slightly less in your operating system.

In binary units a kilobyte is 1024 bytes. A byte is 8 bits.

Drive makers often count 1 GB as 1,000,000,000 bytes, while operating systems count 1 GB as 1,073,741,824 bytes. The difference makes the usable space look smaller.
