About Data Storage Converter
Manufacturers use decimal units — 1 GB is 1,000,000,000 bytes. Operating systems often use binary units, where 1 GiB is 1,073,741,824 bytes. That 7% gap is why a “1 TB” drive shows up as roughly 931 GB.
How to use it
- Enter value, from and to.
- Results update the moment anything changes.

Questions
What does the from option change?
It offers 11 choices — Bits, Bytes, Kilobytes (1000) and Megabytes (1000²) and more. The default is Gigabytes (1000³), which suits most cases; change it when your input or your destination calls for something specific.
