Terms of Use
Last updated: 2026-07-03
1. What This Site Is
EasyFormula is a free educational reference: formula explanations, worked examples, and calculators for math, physics, chemistry, and geometry. It's intended to help with learning, homework, and exam preparation — not as professional, engineering, medical, financial, or certified academic advice. By using this site, you agree to these terms.
2. Accuracy & No Warranty
Content is written and checked carefully (see the About page's "Accuracy & Corrections" section), but formulas, worked examples, and calculator results are provided "as is," without warranty of any kind. Always verify results that matter — a graded assignment, an exam, a real calculation with real consequences — against your course material or another trusted source. If you find an error, please report it.
3. Using the Calculators
The interactive calculators on formula pages run entirely in your browser — the numbers you enter aren't sent anywhere or stored. They're a study aid for checking your own work, not a substitute for understanding how to solve the problem by hand.
4. Content & Intellectual Property
The explanations, examples, and other written content on this site are original, written specifically for EasyFormula (formulas themselves are general mathematical/scientific knowledge and belong to no one). You're welcome to link to any page here. Please don't copy substantial portions of the written explanations elsewhere without asking first — contact usif you'd like to reuse something.
5. Advertising
This site may display advertisements served by Google AdSense to help cover hosting and development costs — see the Privacy Policyfor exactly what that involves. We don't control the content of individual ads and aren't responsible for third-party sites they link to.
6. External Links
Formula pages sometimes cite external references (textbooks, standards bodies, established educational sources). We link to them because we found them useful, not as an endorsement of everything else on those sites, and we aren't responsible for their content or availability.
7. Changes to This Site or These Terms
This site is actively maintained and content is added or corrected regularly. These terms may be updated as the site changes — the "Last updated" date above will always reflect the most recent substantive change.
