Terms of Use

Last updated: November 1, 2026

Using TOOLS411

TOOLS411 provides free online tools — converters, calculators and text utilities — for personal and commercial everyday use. By using this site you agree to these terms. No account is required and no fee is charged.

Accuracy and important decisions

We work hard to make every tool accurate, and each tool page publishes the formula or conversion factors it uses. Results are nevertheless provided "as is", for general information. Displayed results may be rounded. Do not rely on TOOLS411 as the sole source for anything where an error could cause harm or loss — including medical, engineering, construction, legal, tax or financial decisions. Verify important figures with an authoritative source or a qualified professional.

Acceptable use

  • Use the tools for their intended purpose.
  • Do not attempt to disrupt, overload or gain unauthorized access to the site or its hosting.
  • Do not misrepresent TOOLS411 results as certified or official measurements.

Intellectual property

The site's design, text and code belong to TOOLS411 unless otherwise noted. The results you produce with the tools — your converted figures, counts and calculations — are yours to use freely.

Third parties and advertising

Pages may contain advertising served by third parties (such as Google). Advertisements are the responsibility of the advertiser; their presence is not an endorsement by TOOLS411. Links to other websites are provided for convenience, and we are not responsible for their content or practices.

Availability and changes

Tools may be added, changed or removed over time, and the service is provided without a guarantee of uninterrupted availability. These terms may be updated; the current version will always be posted on this page with its revision date.

Liability

To the extent permitted by law, TOOLS411 is not liable for losses arising from reliance on tool results or from use of this site. Nothing in these terms limits liability that cannot be limited by law.
