      Tips & FAQs

      How do I reuse a conversion?
      Copy the page URL to keep the category, units, formatting and entered value. Favorites and recent unit pairs are saved in this browser.
      How accurate are the conversions?
      Conversions use standard base-unit factors, with temperature offsets handled separately.

      • Units use base-10 for data sizes (1 KB = 1000 B).
      • Batch input expects one value per line.

      Privacy

      Conversions run in your browser. The page URL includes your entered value and settings; sharing or opening that URL exposes those values to its recipient. Favorites and recent unit pairs stay in local storage.
