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>
