Calculators for your site and your code

Embed a calculator

Pick a calculator and the language your visitors read, copy the code and paste it where the calculator should appear - an HTML or code block in your site builder is enough. The calculator sizes itself to fit.

<div data-splitgate="pace" data-lang="en">
  <a href="https://splitgate.app/en/tools/hyrox-pace-calculator">HYROX pace calculator</a>
</div>
<script src="https://splitgate.app/embed.js" async></script>

The calculator runs on Split Gate, so it stays up to date without you touching it. It carries a small "Powered by Split Gate" link - please leave it in.
