1. General Information & Accuracy

The calculations, formulas, fluid property data, and results provided on CheCalc are for educational, informational, and preliminary estimation purposes only. While we make every effort to ensure the mathematical accuracy of our algorithms based on established chemical engineering literature, we do not guarantee that the results are entirely error-free, exhaustive, or up-to-date. Engineering models often rely on empirical correlations that may not apply universally to all real-world conditions.

2. No Professional Engineering Advice

The content and output generated by CheCalc do not constitute certified professional engineering advice, consulting, or design services. Our tools are designed to assist—not replace—the rigorous judgment of a qualified, licensed Professional Engineer (PE). You must not use our calculators as the sole basis for final equipment sizing, safety-critical systems, process design, or operational decision-making. All preliminary results must be independently verified using approved industry standards, rigorous simulation software, and peer review.

3. No Warranties

This website and its computational tools are provided strictly on an "as is" and "as available" basis. CheCalc expressly disclaims all representations and warranties, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the website will be uninterrupted, secure, or free from software bugs, nor do we warrant the precise accuracy or reliability of any third-party physical property data referenced in our tools.

4. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall CheCalc, its founders, contributors, or affiliates be liable to you or any third party for any direct, indirect, incidental, special, consequential, or punitive damages. This includes, without limitation, damages for loss of profits, operational downtime, plant failure, design flaws, loss of data, personal injury, or property damage resulting from your use of, or reliance on, our calculation tools—even if we have been advised of the possibility of such damages. By using this website, you agree that the exclusions and limitations of liability set out in this disclaimer are entirely reasonable.
