Permitted Use

You may use this website and its converters for personal, educational and other lawful purposes, and you may link to its public pages. Without our prior written permission, you may not reproduce, republish, sell or redistribute a significant part of the site, or systematically copy our original articles, illustrations, converter interfaces or source code to another website or service.

Nothing in this policy restricts any use permitted by applicable copyright law, such as fair use, fair dealing, quotation, criticism, review or research.

Reporting a Copyright Concern

We respect the intellectual-property rights of others. UnitConversionPlus publishes its own content and does not host material uploaded by visitors. If you believe something on this website uses your copyrighted work without permission, please email baker@unitconversionplus.com with the subject line "Copyright concern". It helps us act quickly if you include:

1. the work you believe has been used without permission, and where it can be seen;
2. the address of each page on our site that you are concerned about;
3. your name and contact details;
4. a statement that you believe in good faith that the use is not authorised by the copyright owner or by law; and
5. a statement that the information in your message is accurate and that you are the copyright owner or are authorised to act for the owner.

We review credible concerns and, where appropriate, remove, correct or credit the material, usually after contacting you for further information. Removing or changing material does not mean that we accept every allegation, and we may decline requests that do not identify a protected work or appear to concern a use permitted by law.

Please consider whether an exception such as fair use or fair dealing may apply before sending a complaint, and take legal advice if you are unsure of your rights. Knowingly making a false claim of infringement may lead to legal liability.
