Frequently asked questions

How precise are the conversions?

We use exact ratios from NIST/SI definitions and render up to 12 significant figures. Results with tiny decimals switch to scientific notation automatically.

Is 1 MB = 1000 KB or 1024 KB?

Both — we show them separately. MB/GB/TB are decimal (1000-based, used by disk manufacturers and network speeds). MiB/GiB/TiB are binary (1024-based, used by operating systems).

Are US and UK gallons the same?

No. 1 US gallon ≈ 3.785 L; 1 UK gallon ≈ 4.546 L. We include both.

Does temperature use exact conversions?

Yes. Celsius, Fahrenheit, and Kelvin use their exact formulas — Fahrenheit = Celsius × 9/5 + 32, Kelvin = Celsius + 273.15.

Can I add custom units?

Not yet — the 50+ built-in units cover ~99% of real-world needs. If you need an unusual unit, reach out.
