How the data storage calculator works
Drive manufacturers use decimal units while operating systems often report binary units, which is why a 500 GB drive shows as 465 GiB.
Formula
1 GB = 10⁹ bytes • 1 GiB = 2³⁰ bytes
Worked example
500 GB equals 500,000,000,000 bytes, or 465.66 GiB.
Frequently asked questions
Why does my new drive look smaller?
