By using Calculators Labs, you agree to these terms. They are written to be readable, not to bury important information in legal language.
1. What This Site Is For
Calculators Labs provides free online calculators for educational, informational, and practical use. The tools cover geometry, volume, finance, fitness, and packaging. They are designed to give fast, accurate answers with clear working steps.
You are welcome to use the calculators for personal, educational, or professional purposes within the scope described on each tool's page.
2. Accuracy and Limitations
We work carefully to ensure formulas are correct and results are reliable. However, calculators involve assumptions, and real-world problems can involve factors a calculator cannot see. Specific limitations by category:
- Geometry and volume calculators assume ideal shapes. Real objects may have irregular dimensions, manufacturing tolerances, or material properties that affect the actual result.
- Finance calculators (break-even point, markup) are planning tools. They do not account for taxes, financing costs, currency fluctuation, refunds, variable demand, or any other factors specific to your business. Do not make significant financial commitments based solely on these results without consulting a qualified accountant or financial adviser.
- Fitness calculators (lean body mass) produce statistical estimates based on population-level equations. They are not a substitute for a professional body composition assessment. Do not use these results to make medical or clinical decisions.
- Packaging calculators provide geometry-based estimates. Actual packaging requirements depend on product fragility, carrier specifications, regulatory requirements, and materials not captured by the calculator inputs.
3. No Warranty
Calculators Labs is provided "as is" and "as available." We make no warranty, express or implied, that the site will be uninterrupted, error-free, or free of harmful components. We reserve the right to update, modify, or take down any calculator or page at any time without notice.
4. Limitation of Liability
To the fullest extent permitted by applicable law, Calculators Labs and its operators are not liable for any direct, indirect, incidental, or consequential damages arising from your use of the site or reliance on any calculator result. This includes, without limitation, losses from business decisions, errors in professional work, or outcomes in academic settings.
5. Acceptable Use
You agree not to:
- Attempt to circumvent, overload, scrape, or disrupt the site or its infrastructure.
- Use the site for any illegal purpose or in violation of any applicable law or regulation.
- Reproduce or republish our calculator tools, code, or content as your own without permission.
Linking to any page on this site is permitted and encouraged.
6. Embed Code
We provide embed code that allows you to display Calculators Labs widgets on third-party websites using an iframe. By using the embed code you agree to the following conditions.
- Attribution is required. The embed snippet includes an attribution link to Calculators Labs. You must not remove, hide, or modify that link. Displaying the widget without the attribution link is a breach of these terms.
- No modification of the embed code. You may resize the iframe to fit your layout, but you may not alter the source URL, strip parameters, or inject content into the iframe in any way.
- We can revoke or change embed access at any time. We reserve the right to modify, disable, or permanently remove the embed feature, or any individual embed URL, at any time and without prior notice. If an embed URL stops working, the iframe will simply stop loading. We are not liable for any disruption this causes to your site.
- No misrepresentation. You may not present an embedded calculator as your own tool, your own product, or as having been built by you or your organisation.
- Compliance on your site. You are responsible for ensuring that embedding our widget complies with your own site's privacy policy, cookie policy, and any applicable laws or regulations in your jurisdiction. The widget loads content from calculatorslabs.com, which means our cookies and scripts (see Privacy Policy) will run inside the iframe on your page.
- No illegal use. The embed code may not be used on pages that contain illegal content, violate intellectual property rights, or are designed to deceive users.
We may audit embed usage at any time. Sites found to be in breach of these conditions may have their embed access disabled without notice.
7. Intellectual Property
The calculator code, interface designs, written guides, and worked examples on this site belong to Calculators Labs. Mathematical formulas themselves are not proprietary — they are in the public domain — but the specific implementations, explanations, and examples we have written are our work.
8. External Links
Some pages link to external resources for reference. We do not control those sites and are not responsible for their content, availability, or practices.
9. Changes to These Terms
We may update these terms as the site grows. The "Last Updated" date at the top of this page will reflect any changes. Continued use of the site after a change constitutes acceptance of the updated terms.
