How it works
What this calculadora actually does
Data Storage Converter is built to give you a clean, explainable answer without the usual wall of ads — type the numbers, read the result, keep moving.
Unit conversions are the dullest way to lose a mark — or crash a rocket. Decide up front which system the answer needs to be in — then convert it and the rest of this page explains what the answer means.
Convert bytes, KB, MB, GB, TB, PB (decimal SI) and KiB, MiB, GiB (binary IEC) — clear on which one your storage sells.
Following the method end to end
Here's what happens when you plug real numbers in.
Convert bytes, KB, MB, GB, TB, PB (decimal SI) and KiB, MiB, GiB (binary IEC) — clear on which one your storage sells.
Moments this tool earns its keep
Data Storage Converter is aimed at people arriving with questions like these:
- "GB vs GiB"
- "MB to KB"
- "TB to GB"
- "What is data storage converter"
- "How to calculate data storage converter"
- "Data storage converter formula"
Where the number stops being useful
Every tool has an edge where it stops being the right answer. Data Storage Converter is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Mistakes we see over and over
Every time you convert it for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Assuming the UK and US versions of the same unit are interchangeable — they're not.
- Typing a comma where the tool expects a dot (or vice versa).
- Rounding early — particularly painful in percentages and compound growth.
- Ignoring the time window: a 'per year' answer makes no sense with a monthly input.
- Treating the answer as private: screenshots are fine, but the URL always reruns cleanly.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- NIST
- IEC 60027-2
Works well alongside
If this question keeps coming up for you, the same cluster of tools usually comes next:
- Bandwidth Converter calculadora — Convert bps, kbps, Mbps, Gbps and bytes/sec, and estimate download times for common file sizes.
- Frequency Converter calculadora — Convert between Hz, kHz, MHz, GHz and RPM — handy for electronics, engines and audio.
How we keep this accurate
Our calculadoras run on pure, unit-tested functions — the same logic lives in the browser and in the CI test suite. When tax rates, thresholds or official figures move, the update lands within 24 hours of the announcement. You can read the editorial policy and corrections policy.
