Data Storage Converter — Binary multiples (1024) from bytes to petabytes

Use this Data Storage Converter to translate digital storage between Bytes (B), Kilobytes (KB), Megabytes (MB), Gigabytes (GB), Terabytes (TB), and Petabytes (PB). Conversions normalize through total bytes using the common binary ladder (each step ×1024), which matches how many operating systems and developer tools label file and volume sizes.

What is binary storage conversion?

Digital storage units are multiples of the byte. In this tool, each step up the ladder multiplies by 1024 (binary IEC-style KiB/MiB/GiB logic, often labeled KB/MB/GB in software). Converting “through bytes” keeps results consistent when you switch between any pair of units or compare vendor quotes.

Why it matters

  • Estimating backup windows, sync jobs, and bandwidth needs starts from knowing the true byte count behind “GB” and “TB”.
  • Developers and SREs reconcile UI labels, database limits, and object storage bills more easily when everything is tied to one byte baseline.
  • Comparing file sizes across archives, VMs, and object storage is faster when you can jump between KB→GB or GB→PB without mental arithmetic errors.

1024 ladder (binary)

  • 1 KB = 1024 B; 1 MB = 1024 KB; 1 GB = 1024 MB; 1 TB = 1024 GB; 1 PB = 1024 TB.
  • Results include total bytes, a clear formula line, step-by-step reasoning, and the same amount expressed in every supported unit.
  • Disk and cloud marketing sometimes use decimal TB (10¹² bytes); this converter uses 1024-based multiples unless you compare labels explicitly.

Binary ladder (reference)

  • 1 B = 1 byte (base)
  • 1 KB = 1024 B
  • 1 MB = 1024 KB = 1,048,576 B
  • 1 GB = 1024 MB = 1,073,741,824 B
  • 1 TB = 1024 GB = 1,099,511,627,776 B
  • 1 PB = 1024 TB = 1,125,899,906,842,624 B

Example conversions

Input Approx. output
500 MB → GB ≈ 0.48828125 GB (binary)
2 TB → GB 2048 GB
1 PB → TB 1024 TB

Popular conversion pairs

MB ↔ GB GB ↔ TB TB ↔ PB KB ↔ MB B ↔ KB

Use cases

  • Sizing uploads, backups, and replication jobs
  • Capacity planning for servers, NAS, and object storage
  • Comparing log archives, database dumps, and media files
  • Explaining file sizes to clients or stakeholders with exact bytes

Input rules

  • Amount must be numeric and ≥ 0.
  • Both source and target units must be selected.
  • Source and target units must differ.

How to use Data Storage Converter

  1. 1 Enter a non-negative numeric amount (decimals allowed).
  2. 2 Choose the source unit (B, KB, MB, GB, TB, PB).
  3. 3 Choose a different target unit.
  4. 4 Run the tool.
  5. 5 Read the converted value, exact byte total, formula, steps, inverse multiplier, and the full per-unit table.

Formula

  • Base: total bytes = input × (bytes per source unit).
  • Target amount = total bytes ÷ (bytes per target unit).
  • Pair multiplier (target per source) = (bytes per source) ÷ (bytes per target).

How results are structured

You get the converted amount, an exact byte total (with scientific notation when huge), a one-line formula, ordered steps, the inverse multiplier for the pair, and a table listing the same data in B through PB so you can cross-check labels quickly.

Who should use this

Developers, DevOps and SRE teams, data engineers, students, and anyone comparing file sizes, quotas, or storage products who wants OS-style binary multiples in one place.

Decimal vs binary labels

Some storage hardware is sold using decimal TB (1 TB = 10¹² bytes). Operating systems often display binary TiB-style numbers using “TB” wording. Use the byte total and the ladder table here to align what you see in the UI with what you calculate.

Frequently asked questions

Quick answers to common questions.

Does this use 1000 or 1024 between KB, MB, and GB?
It uses 1024 between each step (binary multiples), which matches the common software convention for these unit names.
Why show total bytes?
Bytes are the single common ground for every unit. Showing the exact byte count avoids rounding drift when you convert the same figure several times.
Can I convert petabytes?
Yes. PB is supported, and very large byte totals may appear in scientific notation for readability.
Is this free?
Yes. Use it online without signing up.
