No warranty

The calculator is provided "as is" and "as available." The results are produced by a software engine and may contain errors. For high-stakes work (exams, engineering, finance), verify the result against a second source.

Acceptable use

Don't abuse the service — don't try to take it down, scrape it at scale, or use it to attack the underlying infrastructure. The tool is intended for individual, interactive use.

Intellectual property

These terms may be updated. Continued use of the site after a change indicates acceptance of the new terms.
