Terms of Use

Last updated: 17 September 2026

Acceptance of These Terms

By accessing or using calctables.com ("we", "us"), you agree to these Terms of Use. If you don't agree, please don't use the site.

What calctables.com Provides

calctables.com provides free calculators and articles covering finance, health & fitness, math, science, electronics, construction, and everyday conversions, for general informational and reference use.

Not Professional Advice

calctables.com's calculators and articles are informational tools only. They do not constitute tax, legal, financial, medical, or other professional advice, and using them does not create any advisory or professional relationship between you and calctables.com. Always verify figures that affect a financial, medical, or legal decision with a qualified professional — such as your lender, doctor, or accountant — before relying on them.

Accuracy & No Warranty

We build and verify calculators against authoritative reference sources (WHO/CDC/ACSM for health formulas, NIST/SI/IUPAC for physical constants, and textbook-standard financial mathematics for loan and interest calculations) and review them regularly. Even so, reference standards are occasionally revised, and individual circumstances vary. calctables.com is provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, completeness, or fitness for a particular purpose. Results are estimates and may differ from figures produced by your bank, lender, or healthcare provider.

Limitation of Liability

To the fullest extent permitted by applicable law, calctables.com and its team are not liable for any loss, damage, penalty, or claim — direct, indirect, or consequential — arising from your use of, or reliance on, this site or its calculators, including outdated or incorrect results.

Acceptable Use

You agree not to: misuse or attempt to disrupt the site (including scraping at scale, denial-of-service attempts, or bypassing security controls); reproduce, resell, or redistribute calctables.com's calculators, articles, or underlying code without permission; or use the site for any unlawful purpose.

Intellectual Property

The calctables.com name, logo, calculator designs, articles, and site content are owned by calctables.com or its licensors and protected by applicable intellectual property law. You may share links to calctables.com pages freely; you may not copy or republish substantial content without our written permission.

Third-Party Links

calctables.com links to authoritative reference sites for context. We don't control those sites and aren't responsible for their content, accuracy, or availability.

Changes to the Service and These Terms

We may add, change, or remove calculators and content at any time, and may update these Terms as the site evolves. The "Last updated" date above reflects the current version. Continuing to use calctables.com after a change means you accept the updated Terms.

Governing Law

These Terms are governed by the laws applicable to the jurisdiction in which calctables.com is operated, without regard to conflict-of-law principles.
