What this site is

PracticalBench provides free calculators, estimators, converters and similar practical tools, along with explanatory content. The site does not offer accounts, subscriptions, paid services, user-generated public content, or a public API. It is supported by advertising.

Permitted use

You may use PracticalBench's tools for personal or professional reference. Don't attempt to disrupt the service (for example, automated scraping at rates that degrade it for others), circumvent security controls, or use our email addresses to send unsolicited bulk messages.

Intellectual property

Unless otherwise stated, PracticalBench's website design, original code and written content are owned by the site's operator. Tool results you generate are yours to use however you like.

Informational tools and estimates

PracticalBench provides informational tools and estimates only. Results depend on the information you enter and the assumptions described on the relevant tool page. Different inputs or assumptions may produce different results, and no result is guaranteed to be complete, current or suitable for your particular circumstances.

Results are not professional engineering, financial, legal, medical or other professional advice. You should verify important calculations independently and obtain qualified professional advice where appropriate before relying on a result. See our disclaimer for further detail.

Availability

We aim to keep the site available but don't guarantee uninterrupted access. Tools may be added, changed or removed without notice. The site may be taken offline for maintenance or security updates.

External links

Pages may link to external sites or services; we're not responsible for their content, accuracy, or practices.

Liability

To the maximum extent permitted by law, PracticalBench and its operator are not liable for any damage, loss or cost arising from your use of the site or its tools. This includes direct, indirect, incidental, special or consequential damage.

Changes to these terms

If we make material changes to these terms, we'll update this page and the "Last updated" date above. Please review the current version before using the site.
