Top comment
I built this because I was tired of conversion websites that are slow, full of pop-ups, and loaded with tracking scripts. The Conversion Atlas does everything locally in your browser—no data is ever sent to a server. It covers 674 unit converters across 16 categories (length, weight, temperature, speed, volume, etc.), and results update instantly as you type. Tech-wise, it's all vanilla JavaScript with precise formulas—no rounding hacks. The goal was to make something fast, accurate, and completely clutter-free. Would love your feedback on: - Any missing unit types you'd find useful - Performance on mobile - The overall UX Thanks for taking a look!
