Convert for Windows

Convert is a free and easy to use unit conversion program that will convert many of the most popular units.

Hello,

I’m looking for a unit converter written in JS / client-side only that I can self-host / add to a bunch of tools I already use.

I was looking for a suggestion to get something similar to the good old https://joshmadison.com/convert-for-windows/ but that runs a browser.

Thank you for your suggestions.
