Hey Product Hunt! 👋
I built Pro Unit Converter because every unit converter I used was either cluttered, missing the units I needed, or broken on mobile.
So I made one I'd actually want to use:
16 categories, 120+ units — length, weight, temperature, currency (live rates), cooking, pressure, and more
Converts as you type — no button to click
Batch mode — convert a list of values at once
Works offline — installable PWA, no connection needed after first load
Public JSON API — free to use at /api/convert/m-to-ft.json
No signup, no paywalls — just the tool
I'd love your honest feedback. What categories or units are missing? What would make this your go-to converter?
