Terms of Use

Purpose of the site

Engineering Calculator Hub provides free calculators, reference tables and educational guides for engineering work. It is intended for education, preliminary calculations, estimation and reference.

No professional advice and no warranty

Results are produced from published equations and standard property data, and the site is tested against reference values, but it is provided “as is” without warranty of any kind. Calculations are not a substitute for calibrated instruments, approved design documentation, applicable codes and standards, equipment manufacturers’ data, or review by a qualified engineer. You are responsible for checking every result before relying on it for design, safety, commissioning, billing or regulatory purposes.

Limitation of liability

To the fullest extent permitted by law, the owner of this site is not liable for any loss or damage arising from the use of, or inability to use, the calculators, results or guides, including loss of profit, equipment damage or injury.

Acceptable use

You may use the calculators for personal, educational and professional work. Please do not attempt to disrupt the site, scrape it at a rate that affects other users, or republish its content as your own.

Content and intellectual property

The site’s text, design and code are the work of its owner. Standards, equations and property formulations referenced on the site (for example ISO 5167 and IAPWS-IF97) belong to their respective organisations; the site implements published equations and does not reproduce the standards themselves.

Third-party services

The site uses Google Analytics and Google AdSense, and offers optional voluntary support through Razorpay. These services have their own terms and privacy policies; see our Privacy Policy for details. Advertisements do not influence calculation results.

Your data

Calculation inputs and history are processed and stored in your own browser. The site does not require an account.
