The converters themselves
Every converter on Unit Converter — length, weight, temperature, volume, area, speed, time, digital storage, pressure, and energy — runs entirely in your browser. Whatever value you type in is processed locally using JavaScript and never sent to our servers or any third party, because we don't have servers that process it. No tool on this site makes any network request at all.
Analytics
We use privacy-focused, cookie-free web analytics to understand aggregate traffic — which converters are popular and roughly where visitors come from. This doesn't collect personal data or track you individually across sites.
Advertising
This site may show ads served by Google AdSense. Google and its advertising partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this data at policies.google.com/technologies/partner-sites, and opt out of personalized advertising through Google Ad Settings.
Cookies
Unit Converter itself does not set any cookies. Third-party services embedded on the site — currently Google AdSense, when active — may set their own, subject to their own privacy policies linked above.
