Embed Our Calculators

Free calculators and unit converters you can put on your own site with one copy and paste.

Want a calculator or unit converter on your own site, blog, course page or intranet? You can embed ours for free. It runs inside a small frame on your page, does the same sums as the page here, and needs no account, no sign-up and no code beyond one copy and paste.

How to embed

Find the calculator below (or open its page and look for Embed this calculator on your site at the bottom).
Press Copy the code and paste it into the page on your site where you want the calculator (in WordPress use a Custom HTML block).
The frame sizes itself to the calculator, and works on phones.

Terms

Free to use on any website, including commercial and course sites.
Keep the small credit line (“Calculator by Engineer Underground”) that comes with the code. It is how other people find the full page with the worked example and theory.
The embedded calculator is for general information. Please do not present it as your own, and check results against the standards and data that apply to your project.
We may improve or change a calculator over time. The embed always shows the current version.
