UnitToolbox - Universal Unit Converter

Hi everyone 👋 I’m Paweł, an indie developer behind Astro Photons Apps and the creator of UnitToolbox. I built this simple web app because I was frustrated with cluttered, ad-heavy unit converter sites that made a simple task feel complicated. I wanted something fast, clean, and trustworthy - a tool you can open on your phone or laptop and get instant, accurate results in seconds. What makes UnitToolbox different? - Speed & simplicity - no logins, no distractions, just conversions. It's a static website with no server-side languages. - Accuracy - every formula is up-to-date and reliable. - Free forever - I believe tools like this should be accessible to everyone. Right now, UnitToolbox covers the essentials (length, weight, area, volume, temperature, etc.) plus some niche tools for astronomy and engineering - but my goal is to expand it into the most comprehensive online converter out there. I’m proud that this project already helps people around the world with school, work, cooking, DIY, and science. And since I’m a solo founder, every bit of feedback helps me make it better. Would love to hear: - What converters do you personally use the most? - What niche tools would you like to see added next? Thanks for checking out my launch and supporting indie makers ❤
