Hey Product Hunt! 👋
I made measure.cat.
Like many of you, I got completely fed up with the current state of online unit converters. Every time I needed a quick conversion, I had to wade through ad-heavy layouts, cookie banners, sluggish load times, and cluttered interfaces just to get a basic number.
I wanted something different: an incredibly fast, minimalist tool that does the job instantly and leaves you alone.
So I built measure.cat. It covers 1,880 instant conversion pairs across 14 categories—everything from standard lengths and weights to niche data storage, force, and scientific units. Every single pair has its own dedicated permalink, calculation formula, and quick-reference table.
Key focus points:
- 100% free and open to use.
- No accounts, no logins, no paywalls.
- Privacy-first: Zero tracking of your inputs.
I'd love to hear your thoughts, feature ideas, or any niche measurement units you want to see added next! Thanks for checking it out. 🐱📐
