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!

Update, 2 weeks in: thanks to everyone who checked it out! 🙏

Since launch I've been polishing performance and mobile UX. Still looking for feedback, especially any unit categories you're missing.

If The Conversion Atlas saved you a Google search, a review here helps a ton. ⭐

What unit converters are you still missing? (Building The Conversion Atlas)

Hey everyone

I'm the maker of The Conversion Atlas, a free unit converter with 674 converters that runs entirely in your browser (no tracking, no popups, no sign-up).

Two weeks post-launch, I'm planning the next batch of converters and would love input:

Any unit categories you regularly Google that most converters don't cover?
Anything niche, cooking, dev-related (data rates, timestamps), engineering?
