Terms of Use

Effective date: October 9, 2026. These terms explain the purposes and limits of Quirkulator. By using the site, you agree to these terms.

1. What Quirkulator is (and is not)

Quirkulator provides free calculators and converters for educational use and everyday arithmetic. The site was created with AI and automated workflows; its formulas and text have not all received independent expert review. Results depend on the stated units, inputs and assumptions. The tools do not provide medical, financial, legal, structural-engineering or food-safety advice, and using a tool does not create a professional relationship. See our authorship and review disclosures.

2. When to consult a professional instead

Check important results against an appropriate primary source, measurement or qualified professional. For example, an ingredient conversion does not establish safe food handling, and a deflection estimate does not establish a structure's safe load. Follow product instructions and applicable professional guidance.

3. Accuracy and availability

Calculator pages provide formulas, assumptions and references where available. Automated tests and corrections can improve the tools but do not establish that every result is correct. You can report reproducible errors through the contact page. The service is provided "as is" and "as available", subject to any rights that applicable law does not permit us to exclude. We do not guarantee that results are accurate, complete or suitable for your situation, or that the site will be uninterrupted.

4. Acceptable use

You agree not to: scrape or crawl the site at rates that degrade it for others; attempt to breach, probe or overload the service; misrepresent Quirkulator results as professional certifications, medical assessments or legal determinations; or use the site in violation of applicable law. Personal, classroom and editorial use — including quoting and sharing results with attribution — is warmly encouraged.

5. Intellectual property

Rights in protected site materials remain with their respective owners. References and third-party material do not imply endorsement of Quirkulator. You may quote reasonable excerpts of Quirkulator material with attribution and a link, subject to any applicable third-party rights. We do not claim ownership of unit definitions, scientific facts or mathematical methods.

6. Third-party links and ads

Pages may contain links to third-party sites and may display third-party advertising. We are not responsible for the content, policies or practices of third parties; their terms govern your use of their services.

7. Limitation of liability

To the extent permitted by applicable law, Quirkulator and its operators exclude liability for indirect or consequential loss arising from use of the site or reliance on its results. Nothing in these terms excludes liability or rights that applicable law does not allow to be excluded.

8. Changes

We may update these terms; changes take effect when posted on this page with a new effective date. Continued use after changes constitutes acceptance.
