Free Data Storage Converter
Is that backup 500 GB or 500 GiB? Storage math runs on powers of 1,024, and the numbers get confusing fast. This free data storage converter translates between bits, bytes, KB, MB, GB, TB and PB using true binary prefixes, with every equivalent in one table.

How to Use the Data Storage Converter
- Enter a value in the input box above.
- Choose the units to convert from and to — use the ⇄ button to swap them instantly.
- See the result immediately, plus the value converted into every other storage unit in the table below.
- Copy the result with one click to use it anywhere.
Features
Eight storage units from single bits to petabytes, all 1024-based, with live conversion and one-click swapping. Nibble support included for low-level work.
Benefits & Use Cases
Anyone sizing backups, comparing cloud plans, partitioning drives, or studying for IT certs gets exact binary conversions. The table makes it obvious why your “1 TB” drive shows less in the OS.
Tips
Operating systems report GiB (1,024-based) while drive makers advertise GB (1,000-based) — that is the whole missing-space mystery. 1 GiB = 1,073,741,824 bytes.
Frequently Asked Questions
How many MB are in a GB?
1,024 MB per GB in binary units (the kind operating systems use).
How many bits are in a byte?
8 bits per byte — always.
Why does my 1 TB drive show less space?
Makers sell decimal terabytes (10¹² bytes); your OS reports binary tebibytes. 1 TB ≈ 931 GiB.
How many bytes are in a KB?
1,024 bytes per binary kilobyte.
