Embed the BMI calculator on your site

A self-contained BMI calculator that classifies the same number under four standards — WHO, Japan (JASSO), Asia-Pacific (WPRO), and China (WGOC). One line of HTML, no framework, no signup, no tracking. Free to use on any site.

Paste this where you want it

<div id="wc-bmi"></div>
<script src="https://worldcalculators.org/embed/bmi.js" async></script>

The <div> is the mount point; the script renders the widget into it. Both lines are required.
