Free engineering calculators for your website
Every calculator on Engineering Bible can run inside your own page: a course site, a company intranet, a product page or a blog post. It costs nothing, needs no account, and stays up to date by itself, because it loads from this site.
How to embed a calculator
- Open the calculator you want, for example the pipe pressure drop calculator.
- Choose Embed under the calculator. The code is copied for you.
- Paste it into your page where the calculator should appear. In WordPress, use a Custom HTML block.
The code is one iframe and one link back:
<iframe src="https://engineeringbible.com/embed/pipe-flow/" title="Pipe flow and pressure drop" width="100%" height="680" loading="lazy" style="border:0" sandbox="allow-scripts allow-same-origin allow-popups allow-popups-to-escape-sandbox" referrerpolicy="strict-origin-when-cross-origin"></iframe>
<p><a href="https://engineeringbible.com/fluids/pipe-pressure-drop/">Pipe pressure drop calculator</a> by Engineering Bible</p>What you get
- Checked results. Each calculator is tested against textbook examples, standards and hand calculations before every release: 1341 checks across 179 calculators.
- Units your readers use. Every input and result can be switched between metric and US units.
- No tracking and no ads in the embed. The embedded calculator sets no cookies and shows no advertising.
- Safe by design. The iframe runs sandboxed and cannot read or change your page.
- Always current. Fixes and improvements reach your page without you doing anything.
The one condition
Keep the link under the calculator. It credits the work and lets your readers find the formula, the assumptions and the worked example behind the result. You may change the height, the width and the text of the link.

Questions
Can I use the calculators in teaching material or a company tool?
Yes, embedded as above. For printed material, cite the calculator with the citation on its page.
Can I remove the branding or change the colours?
Not in the free embed. Write to contact@engineeringbible.com if you need something different.
Does the embed slow my page down?
It loads lazily, only when a reader scrolls to it, and the calculator itself is small.
