Terms of Use
Effective date: 2026-10-06
By using gravelcalcpro.com you agree to these terms; if you don't agree, please don't use the site. They're deliberately short — this is a free calculator, not a contract negotiation.
The service
GravelCalc Pro provides a free browser-based calculator and reference content about gravel, with no accounts and no guaranteed availability. We may change, suspend, or remove any part of the site at any time. The tool is functional math help, not a commercial measurement service, and results depend entirely on the inputs you enter.
No professional advice
Nothing on this site is engineering, construction, or purchasing advice, and the numbers are estimates, not specifications. Density and price figures are industry-typical values that vary by supplier, stone source, moisture and region. You are solely responsible for verifying quantities, weights, and suitability of materials before ordering or building. See the full disclaimer — it's part of these terms.
Acceptable use and content
Use the site lawfully, don't attempt to disrupt it, and don't republish our content wholesale. You may quote short excerpts with attribution and a link. Automated scraping of the full site, framing it as your own, or misrepresenting the calculations as yours is not permitted. "GravelCalc Pro" and the site's content are protected by applicable intellectual-property law; we claim no ownership of standard engineering formulas.
Limitation of liability
To the maximum extent permitted by law, the site is provided "as is" with no warranties, and we are not liable for damages arising from its use. That includes ordering too little or too much gravel, overloading a trailer, or any construction outcome based on calculator output. Total liability for any claim related to this site is limited to zero dollars — it's a free tool.
Changes and governing terms
We may update these terms as the site evolves; the effective date above changes when we do. Continued use after an update means acceptance. These terms are governed by the laws applicable at the site operator's principal place of business, without regard to conflict-of-law rules.
