Terms of Use and Privacy Policy

Last updated: September 11, 2026

Welcome to ConvertSumo (convertsumo.com, the "Site"). By accessing or using the Site you agree to these Terms of Use and to the Privacy Policy below. If you do not agree, please do not use the Site.

1. What the Site does

ConvertSumo provides free online unit converters and calculators (temperature, length, weight, volume, area, speed, angles and similar). The Site is provided for general informational and educational purposes only.

2. No guarantee of accuracy; not professional advice

We try to keep the formulas and results correct, but we do not guarantee that any result is accurate, complete or suitable for your purpose. Some conversions use rounded factors. Results must not be relied upon where an error could cause harm, loss or damage, for example in engineering, construction, aviation, navigation, trade, cooking for people with allergies, or dosing of medicines.

Any notes shown next to a temperature (for example whether a body temperature is "unlikely to be harmful") are general information only and are not medical advice. Always consult a qualified healthcare professional for medical questions.

3. Permitted use

You may use the Site for personal, non-commercial purposes. You may not:

• copy, scrape, crawl or reproduce the Site's content or pages in bulk, other than by public search engines following our robots rules;
• use automated tools that place an unreasonable load on the Site;
• interfere with the operation or security of the Site;
• use the Site in any way that violates applicable law.

4. Intellectual property

The texts, design and code of the Site belong to the Site owner unless stated otherwise. Mathematical formulas and conversion factors are public knowledge and are not claimed as our property. Third-party names and trademarks belong to their owners.

5. Third-party links and content

The Site may contain links to and content from third-party websites, including advertisements. We do not control and are not responsible for third-party sites, their content or their privacy practices.

6. Advertising (Google AdSense)

The Site is funded by advertising served by Google AdSense and other third-party vendors. These vendors use cookies and similar technologies to show ads based on your prior visits to this and other websites:

• Google uses advertising cookies (including the DoubleClick cookie) to serve ads based on your visits to this Site and other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendors' cookies at www.aboutads.info.
• How Google uses data when you use our Site is described at policies.google.com/technologies/partner-sites.
• Where required by law (for example in the EEA, the UK and Switzerland), a consent banner lets you accept or manage the use of cookies for personalised advertising. You can change your choice at any time via the consent link at the bottom of the page or in your browser settings.

7. Analytics and cookies

We use third-party web analytics services (such as Google Analytics) to understand how visitors use the Site: pages viewed, approximate location, device and browser type, referring site and similar statistics. These services set cookies and process this data on our behalf under their own privacy policies. The data is aggregated and is not used to identify you personally.

Cookies are small text files stored by your browser. You can block or delete cookies in your browser settings; the Site will keep working, but some features and ads may behave differently.

8. What we collect ourselves

The Site does not require registration and has no user accounts. We do not ask for or store your name, email address or other personal details. Our web server may keep standard technical logs (IP address, requested URL, time, browser signature) for security and troubleshooting; these logs are deleted on a regular basis.

If you contact us by email, we use your message and address only to reply to you.

9. Your rights

Depending on where you live, you may have rights to access, correct or delete personal data, or to object to its processing. Because we do not hold personal data about you ourselves, such requests are usually best directed to the third-party services listed above. You can always contact us at the address below and we will help where we can.

10. Children

The Site is not directed at children under 13 (or the age required by local law) and we do not knowingly collect personal information from them.

11. Disclaimer of warranties and limitation of liability

The Site is provided "as is" and "as available", without warranties of any kind, express or implied. To the fullest extent permitted by law, the Site owner shall not be liable for any direct, indirect, incidental, consequential or other damages arising from the use of, or inability to use, the Site or any result obtained from it.

12. Changes

We may update these Terms and this Privacy Policy from time to time. The current version is always published on this page with the date of the last update. Continued use of the Site after changes means you accept the updated terms.
