Convert digital storage between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. The catch with storage is that there are two systems: drive makers use decimal units where 1 KB is 1000 bytes, while operating systems often use binary units where 1 KB is 1024 bytes, which is why a labeled 1 TB drive shows as roughly 931 GB. This converter lets you switch between the two so the mismatch stops being confusing. Pick your source and target units, choose decimal or binary, type a value, and the result updates instantly. It is useful for sizing backups, comparing drives, estimating download times, and cloud quotas. All math runs in your browser, so it is fast, private, and works offline once loaded.

Yes. You can choose decimal units where 1 KB equals 1000 bytes or binary units where 1 KB equals 1024 bytes.
Drive makers use decimal 1000 based units while operating systems often report binary 1024 based units, so the same file shows different sizes.
