💾 Data Storage Converter
Convert any value between bits, bytes, decimal units (KB to PB) and binary units (KiB to PiB), and see the exact byte count behind the result. Handy for sizing volumes, quotas, and backups.
🔢 Bits to Petabytes, Converted
What is a Data Storage Converter?
It translates a storage quantity from one unit to another by routing through bytes, keeping decimal units (powers of 1000) and binary units (powers of 1024) apart. That makes it a fast way to reconcile a drive sold in TB with the GiB your operating system reports, or a quota in MB with a backup in GiB.
Use it for capacity planning and quota maths. A 1 TB drive holds 931.32 GiB, so a plan sized in binary figures from your file manager needs the decimal drive size converted first. Verify against your storage specs and your operating system's reporting.
❓ Frequently Asked Questions
Does this use binary or decimal units?
Both, and it names them apart. KB, MB, GB, TB and PB are decimal: 1 GB is 1,000,000,000 bytes, the way drives, cloud plans and network speeds are sold. KiB, MiB, GiB, TiB and PiB are binary: 1 GiB is 1,073,741,824 bytes. Windows reports disks and folders in binary units but labels them GB, so pick GiB when you copy a figure from File Explorer.
Why does my drive show less space than advertised?
Drive and SSD makers usually use decimal units, where 1 GB means 1,000,000,000 bytes, while your operating system reports in binary units (1 GB = 1,073,741,824 bytes). A '1 TB' decimal drive therefore shows as about 931 binary GB. That gap is the source of the classic 'missing space' confusion.
How many bits are in a byte?
Eight. This converter includes bits and bytes alongside the larger units, so you can move between them directly — useful when you're translating between storage figures (bytes) and network or bus speeds (bits).
