What you type

Unit conversions and calculations happen in your browser, and the numbers you enter are not stored by us. Your last-used units, currencies and rounding are saved in your browser’s local storage so the tools open where you left off. You can clear this at any time in your browser settings.

Exchange rates

Currency pages get rates from our own server, which fetches them from ExchangeRate-API and historical rates from the European Central Bank via Frankfurter. Your browser doesn’t contact those providers directly.

Advertising and cookies

This site shows ads from Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can learn how Google uses information at policies.google.com/technologies/partner-sites and opt out of personalised ads at google.com/settings/ads. Visitors in the UK, EEA and Switzerland are asked for consent before personalised ads are shown.

Analytics

We use Cloudflare Web Analytics to count visits and see which tools are used. It doesn’t use cookies and doesn’t track you across websites.
