- Which unit converter should I use?
- Use Unit Converter for broad measurement sets and Temperature Converter for °C/°F/K focused work.
- Are currency rates live?
- Currency conversion depends on the rates available to the tool at request time. Treat outputs as planning estimates, not bank settlement figures.
- Do converters work offline?
- Most conversion math runs in your browser after the page loads. A short first load still needs network access to fetch the tool page.
