Privacy policy

Metric Conversion Tools provides free browser-based unit calculators and measurement reference articles. You can use the calculators without creating an account. The numbers and unit selections you enter are processed by JavaScript in your browser and are not submitted to our server as calculator inputs.

Who operates this site

Metric Conversion Tools is operated by an independent site owner. Questions about this policy or the handling of information associated with the site may be sent through the contact page. This policy covers metricconversiontools.com and does not replace the separate privacy policies of services linked from the site.

Information we collect

The converter runs in your browser. We do not provide user accounts and do not ask for your name, payment information, or account credentials to perform a conversion. Like most websites, the hosting, analytics, security, and advertising services used here may process technical request and usage information. That information can include an IP address, date and time of access, requested page, referring page, browser and device type, operating system, approximate location derived from an IP address, cookie or similar identifiers, ad impressions, and interactions with site content or advertising.

If you email the site owner, the message contains the email address and other information you choose to provide. Please do not include passwords, financial account details, government identifiers, health information, or other sensitive data in a support message.

Analytics and advertising

This site uses Google Analytics to understand site usage and Google AdSense to show advertising. Google Ads conversion tracking may measure how visitors arrive from advertising campaigns. These services can process standard usage data such as pages visited, approximate location derived from an IP address, device and browser characteristics, ad impressions, ad clicks, and identifiers stored in cookies or similar technologies. The measurement values you type into the converter are not deliberately included in analytics events because conversions are calculated locally in your browser.

Cookies and ad personalization

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info. You can also block or delete cookies through your browser settings; the converter works fully with cookies disabled.

Hosting and performance measurement

The site is hosted by Vercel. Hosting infrastructure may process standard request data, such as an IP address, user agent, requested path, response status, and timing information, to deliver pages, maintain reliability, diagnose errors, and protect against abuse. Vercel Web Analytics is also used for aggregate page-visit measurement.

How we use information

Legal bases and choices

Privacy laws differ by location. Where a legal basis is required, technical processing needed to deliver and secure the site is based on legitimate interests in operating a reliable service; handling an email is based on responding to the request you initiated; and non-essential advertising or analytics cookies are used according to the consent choices presented where required. You can decline or withdraw optional cookie consent through the available consent controls and browser settings. Blocking cookies does not prevent the core conversion calculations from working.

Sharing and service providers

Information is not sold directly by the site owner. Technical and usage information may be processed by service providers that help host, secure, measure, or monetize the site, including Vercel and Google. Those providers act under their own terms and privacy documentation and may use subprocessors. Information may also be disclosed when reasonably necessary to comply with law, protect the site or its users, investigate abuse, or respond to a valid legal request.

Retention

The site owner keeps contact messages only as long as reasonably needed to respond, maintain a record of a correction, protect the site, or meet applicable obligations. Hosting, analytics, and advertising providers set their own retention periods and controls. Because the calculator does not create an account or save a conversion history for you, there is no user conversion archive maintained by the site to delete.

International processing

Vercel, Google, and their service providers may process information in countries other than the one where you live. Those countries may have different privacy laws. The relevant provider policies describe their transfer mechanisms and safeguards.

Your privacy rights

Depending on where you live, you may have rights to ask about, access, correct, delete, restrict, or object to certain processing of personal information, or to withdraw consent. Use the contact page to make a request concerning information controlled by the site owner. Requests about data controlled independently by Google, Vercel, or another provider should be directed to that provider. We may need enough information to understand and verify a request, but you should not send sensitive identification documents unless they are specifically and securely requested.

Children

This general-audience reference site is not directed to children for the purpose of collecting personal information, and it does not offer accounts or knowingly request personal details from children. If you believe a child has sent personal information in a message, contact the site owner so the situation can be reviewed.

Security

Reasonable technical and organizational measures are used to operate the site, but no internet transmission or storage system can be guaranteed completely secure. Avoid sending sensitive information through ordinary email.

Third-party policies

Google processes analytics and advertising data under its own privacy policy. How Google uses information from sites that use its services is described at policies.google.com/technologies/partner-sites.

Changes to this policy

This policy may be updated when the site, its service providers, or legal requirements change. The “last updated” date at the top identifies the current version. Material changes will be reflected on this page before or when they take effect.
