Support and contact

Contact UnitConversion.free: support, bug reports, and unit requests

Last updated:

UnitConversion.free is a single-author project operated by Kevin Kinnett. This page lists the supported contact channels and what to send to each one. All inbound messages are read by the operator personally.

Contact channels

  • General questions and feedback: [email protected]. Use this for anything that doesn't fit a more specific channel: site feedback, content suggestions, partnership inquiries.
  • Bug reports and incorrect results: [email protected]. Include the page URL, the input you entered, the result the calculator returned, and the result you expected. Screenshots help.
  • Privacy and data questions: [email protected]. Use this for data-access, data-deletion, or any privacy-related concern. Per the privacy policy, the site collects no personally identifying information server-side, but if your question involves analytics or AdSense behavior, this is the channel.
  • Legal and terms questions: [email protected]. Use this for issues related to the terms of service, accuracy disclaimers, or intellectual property concerns.

Response expectations

This is a single-author project, not a staffed support desk, so response times vary. Most messages get a reply within 1-3 business days. Bug reports and "the result is wrong" reports are prioritized over feature requests because incorrect results can lead users to bad decisions.

For the fastest resolution on a bug report, send the specific URL, the input you used, and what you expected to see. The operator can usually reproduce a reported issue in a few minutes when the inputs are exact, and the fix tends to land in the next deploy.

What kinds of requests are welcomed

New unit pairs and measurement categories. If a unit isn't supported, or if a specific pair-conversion deserves its own page with a custom value table, send that request to [email protected]. Examples of pair pages already live: meters to feet, Celsius to Fahrenheit, kg to lbs, km to miles, liters to gallons, MPG to L/100km. Requests for similar coverage in other dimensions are welcome.

Editorial corrections. If a fact, formula, or historical note on the site looks wrong, please flag it. The site cites the authoritative references (NIST SP 811, the BIPM SI brochure) but content can drift or contain typos.

Accessibility issues. If a page is hard to use with a screen reader, keyboard navigation, or at a specific zoom level, that's worth reporting. The site is single-author and accessibility issues won't catch themselves.

Operator

The site is operated by Kevin Kinnett, a senior software engineer based in the United States. Kevin's broader site is at kevinkinnett.com, including his bio and contact information. See the about page for more on the methodology behind UnitConversion.free.
