Frequently asked questions
How accurate are the conversions?
Linear conversions are computed from precise factors and rounded to 8 decimal places; temperature uses exact formulas rounded to 4.
Can I convert between categories?
No — the dropdowns only show units within the selected category, since cross-category conversion isn't meaningful.
Is my data sent anywhere?
No — conversion runs entirely in your browser.
