1. General disclaimer
The information and calculation tools on aionlinecalculator.com (the "Site") are provided for general informational and educational purposes only. While we make reasonable efforts to verify each calculator against published international standards (IEC, NEC, ASME, ACI, BS, AS/NZS, AISC), we make no warranty — express or implied — regarding the accuracy, completeness, currency, suitability, or availability of any calculator output for any specific purpose.
Use of any calculator on this Site is entirely at your own risk. By using the Site, you acknowledge and accept this disclaimer in full.
2. Engineering calculations — professional review required
Critical safety notice: Engineering calculators on this Site (cable sizing, voltage drop, short-circuit current, transformer sizing, beam deflection, concrete design, foundation load, retaining wall, conduit fill, motor starting current, heat exchanger, pipe sizing, pump head, etc.) implement formulas from published standards. Calculator outputs MUST NOT be used as the sole basis for design, installation, construction, or operational decisions.
Before any professional use:
- Verify the result against the current edition of the cited standard.
- Apply jurisdiction-specific code amendments (your local electrical code, building code, etc.).
- Consider site-specific conditions not modeled by the calculator (ambient temperature, soil conditions, voltage stability, harmonic content, etc.).
- Obtain review and sign-off by a licensed Professional Engineer (PE), Chartered Engineer (CEng), or equivalent registered professional in your jurisdiction.
- Comply with all applicable safety regulations (OSHA, IEC, NFPA, EU Directives, your country's equivalents).
We accept no liability for damages, injuries, equipment failure, fines, code violations, project delays, or other losses arising from use of calculator outputs without independent professional verification.
3. Medical and health calculations — not medical advice
This Site does not provide medical advice. Health calculators (BMI, BMR, body fat percentage, calorie needs, ideal weight, water intake, waist-to-hip ratio) provide general informational estimates based on widely-used population formulas (WHO, Mifflin-St Jeor, US Navy, Robinson, Hamwi, etc.). They cannot substitute for individualized clinical assessment.
Calculator outputs:
- Are not a diagnosis.
- Are not a treatment plan.
- Do not account for individual medical history, medications, conditions, athletic build, body composition variations, pregnancy, age extremes, or genetic factors.
- Should not delay or replace consultation with a licensed physician, registered dietitian, or qualified healthcare professional.
If you are experiencing a medical emergency, contact your local emergency services immediately. Do not use this Site for emergency medical decisions.
4. Financial calculations — not financial advice
Financial calculators (loan EMI, SIP returns, compound interest, savings goals, retirement planning, tip and split, discount, GPA) are educational estimates only. They do not constitute financial, tax, investment, or legal advice.
Actual loan payments, investment returns, taxes, and fees depend on:
- The specific contract terms offered by your bank, lender, or financial institution.
- Variable interest rates, indexation, prepayment penalties, processing fees, and insurance.
- Local tax law (income tax, capital gains tax, GST/VAT, withholding tax).
- Market conditions, currency fluctuations, and credit conditions outside our model.
- Personal circumstances we cannot model (existing debt, dependents, employment stability, risk tolerance).
Always read the full terms of any financial product and consult a licensed financial advisor, certified public accountant, or qualified tax professional before making decisions involving significant sums.
5. Limitations of accuracy
Despite our verification process, the Site may contain errors. Sources of potential inaccuracy include:
- Standard revisions: Standards bodies (IEC, NEC, ASME, ACI, BS, AS/NZS) periodically revise their standards. A calculator implemented against the 2020 edition may produce different results than the 2025 edition.
- Boundary conditions: Standards have validity ranges. Inputs outside the validated range (extreme temperatures, very small or very large sizes, atypical materials) may yield meaningless results.
- Implementation bugs: Despite testing, software bugs can occur. Cross-check critical calculations.
- User input errors: Wrong unit selection, decimal misplacement, or misunderstood input fields produce wrong outputs. The calculator cannot detect when you've entered a value that's wrong but mathematically valid.
- Browser/device variations: Floating-point arithmetic precision varies slightly across browsers and devices.
If you suspect a calculation error, please report it via our contact page — we treat reported errors as urgent and respond same-day.
6. Third-party content and links
Calculator pages cite external sources (IEC, ASME, ACI, NEC, IEEE, peer-reviewed research, Wikipedia, manufacturer datasheets, regulatory bodies). These are linked for your convenience and verification. We are not responsible for the accuracy, currency, content, advertising, or privacy practices of external sites. Inclusion of a link does not constitute endorsement of the linked party or its content.
7. Advertising disclosure
This Site is supported by display advertising via Google AdSense. Advertisements are selected by Google based on Google's algorithms and your prior browsing history (subject to your ad-personalization settings). We do not control which specific ads appear and do not endorse advertisers. Disputes regarding ad content should be directed to Google or the advertiser.
The presence of an advertisement does not constitute editorial endorsement. Editorial content (calculator implementations, written explanations, FAQs, references) is independent of advertising.
8. AI-generated answers and citations
This Site is referenced by AI assistants (ChatGPT, Claude, Perplexity, Gemini, Copilot) and search-engine AI features (Google AI Overviews, Bing Copilot). When an AI assistant cites this Site, the AI's summary may simplify, omit context, or introduce paraphrasing artifacts that could affect accuracy. Always verify by visiting the original calculator page on aionlinecalculator.com before relying on an AI summary.
9. Indemnification
By using this Site, you agree to indemnify and hold harmless AI Calculator, its operators, and contributors from any claim, damage, loss, liability, cost, or expense (including reasonable legal fees) arising from your use or misuse of any calculator output, your violation of these terms, or your violation of any law or third-party right.
10. Updates to this disclaimer
We may update this disclaimer at any time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the Site after changes constitutes acceptance of the updated disclaimer.
