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.
