Contact

We read every message. This is a static site with no contact form and no tracking, so email is the way to reach us.

Corrections and source questions

If a figure looks wrong, we want to know. Accuracy is the entire point of this site. Email corrections@trustthecalcs.com and include the page, the number in question, and the standard or datasheet you are relying on. Citing a primary source lets us verify and fix it quickly. See how we handle these in our editorial policy.

General enquiries and calculator requests

For everything else, a calculator you would like us to build, a partnership, or feedback, email hello@trustthecalcs.com. If you are requesting a new tool, tell us the standard or table it should be based on; that is where we start.

What we cannot do

We cannot provide engineering advice, review your drawings, or size a structural element for your project. Our tools estimate material quantities for preliminary planning only; anything structural belongs with a qualified professional working from your specifics and local code.
