About this unit converter
Temperature uses exact formulas; other categories normalize to SI base units. Searchable selects, pinned units, keyboard shortcuts and a multi-target table make it fast for power users. Output uses your locale’s separators automatically.
Is my data private?
Yes. Everything runs locally in your browser. Favorites, Recents, and pinned units are saved to your device via
localStorage; nothing is uploaded.
How accurate are conversions?
Temperature uses exact formulas; other categories convert via SI base units and precise factors. The Decimals setting controls rounded display; locale formatting doesn’t change internal precision.
Can I export results?
Yes. Open Advanced → click CSV to export all targets, or click any row to copy a single value. You can also copy the main result with the Copy button.
How do favorites and pins work?
Use Save Pair to add a favorite conversion (from→to). Pin up to five units per category to keep them at the top of the selectors. Both are stored locally and can be cleared anytime.
How do I share a setup?
Click Copy Shareable Link. The URL includes category, units, amount, and precision so others open the same view instantly.
