Terms and legal disclaimer
Use calculator results as estimates, then verify what controls your decision
By using Metal Calculators, you agree to use the tools and content reasonably and to check important inputs and results against the documents, measurements, and approvals that govern your work.
Results are theoretical estimates
Results are calculated from the values you enter and published or custom density data. They can differ from actual weight because of material variation, tolerances, coatings, fabrication, fittings, packaging, measurement, and rounding.
No quotation, delivery, approval, or settlement guarantee
A result or page is not a quotation, delivery guarantee, material certificate, engineering approval, safety approval, or commercial settlement value. Confirm critical values with the supplier, applicable documents, qualified professionals, and actual weighing where required.
External sources retain their own scope
Links and citations help explain formulas, conversions, densities, and examples. External publishers control their own material, availability, revisions, and terms. Check the original source when its exact scope matters.
Use the service reasonably
Do not misuse the site, interfere with its operation or security, attempt unauthorized access, or use automated traffic in a way that unreasonably burdens the service. You remain responsible for how you use the results.
Site content and intellectual property
The Metal Calculators name, original interface, explanatory text, and other original site materials are protected by applicable intellectual-property rights. Third-party standards, publications, names, and marks remain the property of their respective owners.
