Frequently asked questions
Does the weight converter work offline?
Yes — the conversion runs entirely in your browser with no server involved, so it works even without an internet connection once the page is loaded.
How accurate are the conversions?
All units are defined by their exact SI relationships, so results are accurate to the last digit your screen can show. Cooking-style units (cups, teaspoons) use the standard US definitions.
Is there a limit on how many conversions I can do?
None. Use it as many times as you like — it is free, unlimited, and requires no account.
