Terms of Service
Last updated: February 9, 2026
By using Trades Calcs (tradescalcs.com), you agree to these terms. If you do not agree, please do not use the site.
Use of This Site
Trades Calcs provides free, browser-based calculators and educational content for construction trade professionals and enthusiasts. You may use the site for personal, educational, and professional reference purposes. You agree not to misuse the site, attempt to interfere with its operation, or use automated tools to scrape or copy its content.
Calculator Accuracy Disclaimer
The calculators on this site produce estimates and reference values only. They are not a substitute for professional engineering judgment, licensed contractor expertise, or official code compliance verification. While we strive for accuracy, results may not account for every variable in your specific situation.
Calculators that reference building codes — including the National Electrical Code (NEC), International Plumbing Code (IPC), Uniform Plumbing Code (UPC), and ASHRAE standards — are provided for educational and reference purposes. These calculators do not replace looking up the actual code. Adopted codes, local amendments, and edition years vary by jurisdiction. Always verify requirements with your local authority having jurisdiction (AHJ) before performing work.
You assume full responsibility for how you use calculator results. Trades Calcs is not liable for any damages, code violations, failed inspections, equipment damage, or injuries resulting from reliance on calculator outputs.
Educational Content Disclaimer
Blog articles, theory sections, and explanatory text on this site are provided for educational purposes. They are written to help tradespeople, apprentices, and homeowners understand concepts and formulas — not to serve as definitive code interpretations or installation instructions. Always follow manufacturer specifications, local codes, and the guidance of licensed professionals.

All content on Trades Calcs — including text, calculators, design, graphics, and code — is the property of Trades Calcs and is protected by applicable intellectual property laws. You may not reproduce, distribute, or create derivative works from this content without written permission, except for reasonable personal use (such as printing a result for a job site reference).
