Terms of use
Effective July 14, 2026.
Operator and acceptance
CalcularLitros is a project operated by Jaime Castillo from Spain and can be used without registration. By browsing or using the tools, you accept these terms where they apply. If you disagree, stop using the website.
Free service
The site provides volume calculations and educational material without charging visitors. It may be funded by advertising. Use does not create an account, purchase or individually commissioned professional service.
What the calculations cover
Formulas model ideal geometric shapes using the values entered. Usable capacity can differ because of walls, irregular profiles, equipment, displacement, slopes, tolerances or fill level. Check units and internal dimensions before relying on a result.
User responsibility
You decide how to use each result. Figures do not replace plans, certificates, manufacturer specifications or qualified advice where structures, pressure, hazardous substances, dosing, health, safety, regulation or significant expense are involved.
Permitted and prohibited use
You may use the calculator for legitimate personal or professional purposes and link to public pages. You must not introduce malware, bypass security, create abusive automated traffic, manipulate advertisements, impersonate others, mass-extract content or interfere with the service or its users.
Intellectual property
The brand, design, original text, illustrations and code belong to their respective owners and are protected. Short attributed quotations are allowed within legal limits. These terms do not grant a license to substantially reproduce, resell or pass off a copied service as your own.
Advertising and external links
Google AdSense advertisements and external links may lead to independent services. Their appearance is not a guarantee, approval or personal endorsement. Each third party is responsible for its products, terms, security and data practices.
Accuracy, changes and availability
Formulas and content are reviewed carefully, but complete freedom from error and uninterrupted availability are not promised. Functions may be corrected, expanded, suspended or withdrawn for maintenance, security or improvement without retroactively changing rights that have already arisen under law.
Legal limits on liability
To the extent permitted by law, the operator is not responsible for decisions made without suitable verification or harm caused by incorrect inputs and use outside the informational purpose. Nothing in these terms excludes liability that cannot lawfully be limited.
Law and contact
Spanish law governs these terms without removing mandatory consumer or user rights or imposing a court other than one competent under applicable law. Questions and notices may be sent to info@calcularlitros.com.
