Disclaimer

Last Updated: September 08, 2026

AjaxCalculators.com is independently owned, managed, developed, tested, reviewed, and maintained by Arefin Bappy, the website’s Owner and Admin.

The calculators, converters, estimates, examples, explanations, and other information provided on AjaxCalculators are intended primarily for general informational and educational purposes.

Calculator Development and Methodology

AjaxCalculators aims to design each calculator using an established, widely accepted, or otherwise appropriate calculation method for its intended purpose.

Depending on the calculator, the methodology may be based on:

  • mathematical formulas;

  • recognised scientific equations;

  • accepted conversion relationships;

  • financial formulas;

  • statistical methods;

  • published guidelines;

  • official reference values;

  • technical standards;

  • recognised estimation methods; or

  • other reputable sources appropriate to the subject.

Some calculations may have more than one accepted formula, standard, or methodology.

Where different accepted methods could materially affect the result, AjaxCalculators aims to identify the method used by the specific calculator.

Individual Testing and Review

Each AjaxCalculators calculator is individually tested and reviewed by the Admin.

Testing is selected according to the type of calculator and may include:

  • manually calculated examples;

  • known results;

  • published examples;

  • standard input values;

  • decimal values;

  • zero values;

  • negative values where applicable;

  • large or small values;

  • different measurement units;

  • unit conversions;

  • invalid inputs;

  • incomplete inputs;

  • boundary conditions;

  • rounding behaviour;

  • desktop functionality;

  • mobile functionality; and

  • general usability.

The purpose of this testing is to confirm that the implemented calculator behaves consistently with its intended formula or methodology.

However, testing cannot guarantee that every calculator will always produce a result that is correct or appropriate for every possible situation.

Sources and Reference Information

Where a calculator depends on external information, AjaxCalculators aims to use reputable sources appropriate to the subject.

These may include:

  • government agencies;

  • official organisations;

  • scientific organisations;

  • professional bodies;

  • universities;

  • peer-reviewed research;

  • recognised technical standards;

  • established reference materials; and

  • official documentation.

Where appropriate, individual calculator pages may identify the formula, methodology, assumptions, and sources used.

AI-Assisted Development

Artificial intelligence may be used as part of the Admin’s website-development workflow.

AI may assist with tasks such as:

  • coding;

  • debugging;

  • identifying potential programming issues;

  • suggesting test cases;

  • organising research;

  • structuring technical information;

  • improving interfaces; and

  • assisting with supporting content.

AI-generated code, formulas, references, explanations, or suggestions are not automatically treated as accurate.

The Admin remains responsible for reviewing the implementation, testing calculator functionality, checking the intended calculation method, and deciding what is published on AjaxCalculators.

AI assistance does not replace human review.

No Guarantee of Absolute Accuracy

AjaxCalculators makes reasonable efforts to provide accurate and useful calculators, but does not guarantee that every:

  • result;

  • formula;

  • conversion;

  • estimate;

  • reference value;

  • explanation;

  • source;

  • classification; or

  • website feature

will always be completely accurate, current, complete, or suitable for every user or situation.

Calculator results may be affected by factors such as:

  • incorrect or incomplete user inputs;

  • measurement accuracy;

  • rounding;

  • assumptions;

  • differences between accepted calculation methods;

  • regional standards;

  • changing laws or regulations;

  • updated scientific information;

  • updated official guidance;

  • changes in reference values; or

  • limitations inherent in the calculation model.

Users should consider these factors when interpreting calculator results.

Different Calculators May Produce Different Results

Two calculators designed for the same general purpose may produce different results without either calculator necessarily being incorrect.

Differences may arise because of:

  • different accepted formulas;

  • different reference values;

  • different assumptions;

  • different rounding methods;

  • different classifications;

  • different regional standards; or

  • different methodologies.

Where the selected methodology is important, users should review the calculation method and assumptions described on the relevant calculator page.

No Professional Advice

The Admin of AjaxCalculators is a professional web developer responsible for the technical development, testing, and review of the website.

The Admin does not claim to be a doctor, financial adviser, lawyer, engineer, accountant, tax professional, dietitian, pharmacist, or other regulated professional through AjaxCalculators unless a specific professional qualification is expressly stated.

The website therefore does not provide personalised professional advice.

Calculator results should not replace appropriately qualified professional guidance when professional advice, diagnosis, assessment, approval, or judgment is required.

Health and Medical Calculators

Health-related calculators are intended for general informational and educational purposes.

They are not intended to provide:

  • medical diagnosis;

  • medical treatment;

  • emergency medical guidance;

  • medication recommendations;

  • individual medical assessments; or

  • substitutes for healthcare professionals.

Health conditions and individual circumstances can involve factors that cannot be represented fully by an online calculator.

If you have concerns about your health, symptoms, medication, or treatment, consult an appropriately qualified healthcare professional.

For medical emergencies, contact your local emergency service.

Financial Calculators

Financial calculators provide estimates based on the information entered by users, selected formulas, and stated assumptions.

They do not constitute personalised:

  • financial advice;

  • investment advice;

  • tax advice;

  • accounting advice;

  • insurance advice; or

  • legal advice.

Financial rules, interest rates, taxes, fees, regulations, and market conditions may change.

Important financial decisions should be independently verified and, where appropriate, discussed with a qualified professional.

Construction and Technical Calculators

Construction, material, engineering-related, and other technical calculators can provide useful estimates, but real-world projects may depend on additional factors that cannot be represented completely by an online calculator.

These factors may include:

  • site conditions;

  • material specifications;

  • structural requirements;

  • building regulations;

  • local codes;

  • manufacturer requirements;

  • safety requirements;

  • professional design;

  • waste factors; and

  • project-specific conditions.

Users are responsible for checking applicable codes, standards, specifications, and professional requirements before relying on calculator results for real-world projects.

Educational, Scientific and Mathematical Calculators

Mathematical and scientific calculators are designed to implement established formulas or methods where applicable.

However, conventions, notation, rounding rules, assumptions, and accepted methodologies can differ between educational institutions, publications, jurisdictions, and disciplines.

Users should verify results against the requirements of their particular assignment, course, publication, institution, or professional context where necessary.

User Responsibility

Users are responsible for:

  • entering accurate information;

  • selecting appropriate units;

  • understanding important assumptions;

  • checking results before making consequential decisions;

  • reviewing calculator-specific methodology where relevant;

  • consulting original or official sources when necessary; and
