Unit conversion
Data Storage Converter
Convert digital storage between bytes, kilobytes, megabytes, gigabytes and terabytes, in both decimal and binary units.
Result
Decimal units (KB, MB, GB) use powers of 1000; binary units (KiB, MiB, GiB) use powers of 1024. Drive manufacturers use decimal, operating systems often report binary, which is why a 500 GB drive shows as about 465 GiB.

About this calculator
Why does my 1 TB drive show as 931 GB?
The manufacturer counts 1 TB as 1,000,000,000,000 bytes (decimal). Your operating system divides by 1024 three times and reports 931 GiB, usually labelled 'GB'. Nothing is missing: the two are just different units.
What is the difference between a bit and a byte?
Eight bits make one byte. Network speeds are quoted in bits per second and file sizes in bytes, so a 100 Mbps connection transfers about 12.5 MB per second.
