Terms of Use

Last updated: August 2026

Welcome to EngiBench. These Terms of Use govern your access to and use of the EngiBench website, engineering calculators, technical tools, reference content, and related services. By using this website, you agree to these Terms. If you do not agree with them, please do not use the website.

1. About EngiBench

EngiBench provides engineering calculators, technical tools, educational explanations, formulas, reference information, and related resources for general engineering and technical use.

The website is intended to support preliminary calculations, learning, estimation, comparison, and technical review. It is not intended to replace project-specific engineering analysis, professional judgment, manufacturer requirements, applicable standards, codes, regulations, or legally required professional services.

2. Use of the Website

You may use EngiBench for lawful personal, educational, professional, and internal business purposes, subject to these Terms.

You agree not to use the website in a way that:

  • violates any applicable law or regulation;
  • interferes with the operation, security, or availability of the website;
  • attempts to gain unauthorized access to systems, accounts, or data;
  • uses automated methods to overload, disrupt, scrape, reproduce, or redistribute the website in a manner that harms EngiBench or other users;
  • misrepresents EngiBench content, calculations, or references as an official approval, certification, engineering stamp, or regulatory determination.

3. Engineering Calculators and Technical Content

EngiBench calculators are designed to perform calculations using the equations, assumptions, unit conversions, and input values described on each page. Results depend on the accuracy and suitability of the information entered by the user.

Engineering conditions can vary significantly by application. A result that is mathematically correct for the selected inputs may still be unsuitable for a specific project if the wrong assumptions, operating conditions, fluid properties, equipment data, standards, reference points, or boundary conditions are used.

You are responsible for reviewing the calculation method, inputs, units, assumptions, and limitations before relying on a result.

4. No Professional Engineering Advice

Information on EngiBench is provided for general engineering, technical, and educational purposes. Use of the website does not create an engineer-client, consultant-client, contractor-client, or other professional relationship.

EngiBench does not provide professional engineering certification, design approval, code compliance approval, equipment approval, safety approval, or regulatory approval through the website.

Where a decision affects safety, legal compliance, equipment selection, structural integrity, electrical protection, pressure systems, hazardous processes, public infrastructure, or other high-consequence applications, consult a qualified professional and the applicable standards, codes, regulations, and manufacturer documentation.

5. Accuracy and Availability

EngiBench aims to provide accurate formulas, unit conversions, calculation logic, references, and technical explanations. However, we do not guarantee that all content is error-free, complete, current, or suitable for every application.

Engineering references, regulations, standards, external websites, product information, and technical requirements may change over time. Users should verify current requirements from the original authoritative source when accuracy or compliance is important.

We may update, modify, correct, suspend, or remove any calculator, page, feature, formula, reference, or other content without notice.

6. User Responsibility

You are responsible for determining whether a calculator or technical method is appropriate for your intended use. This includes confirming:

  • the correct engineering equation or calculation mode;
  • the correct unit system and unit conversions;
  • the accuracy of entered values;
  • the validity of assumptions and operating conditions;
  • the relevance of applicable codes, standards, regulations, and manufacturer data;
  • whether independent review or professional engineering approval is required.

7. References and Third-Party Sources

EngiBench may reference or link to government agencies, standards organizations, manufacturers, educational resources, technical publications, and other third-party websites.

These links are provided for reference and convenience. EngiBench does not control third-party websites and is not responsible for their content, availability, accuracy, security, privacy practices, or future changes.

A link or citation does not imply endorsement, partnership, sponsorship, or approval by the referenced organization unless explicitly stated.

8. Intellectual Property

Unless otherwise stated, the design, layout, written explanations, original graphics, calculator interfaces, and original website content on EngiBench are protected by applicable intellectual property laws.

You may use calculator outputs and reasonable excerpts of technical information for your own lawful work. You may not reproduce, republish, copy, resell, mirror, or distribute substantial portions of the website or its original content as a competing service without permission.

Third-party names, trademarks, publications, standards, and referenced materials remain the property of their respective owners.

This limitation includes decisions made using calculation results without appropriate verification, engineering review, manufacturer confirmation, or compliance review.

11. Changes to These Terms

We may revise these Terms of Use from time to time. Updated Terms will be posted on this page with a revised “Last updated” date. Continued use of EngiBench after changes are posted constitutes acceptance of the updated Terms.
