About this version
Unit Converter Assistant runs entirely in the browser. It recognizes common unit names, abbreviations and phrases, detects the requested conversion and performs the calculation locally. It does not require an API key. Currency is intentionally excluded because exchange rates change continuously and require live financial data.
