Rosetta vs Unit Converter

Translate measurements instantly. A calm, ad-free unit converter for everyday checks — currency, weight, length, temperature, and ten more categories. Tap either side to make it the active value; both cards are first-class, so you can convert in either direction with one tap. Star up to ten favorites for one-tap reuse from the home screen. Currency rates come from the European Central Bank — cached after your first fetch, so they keep working offline. THIRTEEN CATEGORIES • Currency — 165 ISO currencies, ECB-sourced rates • Length — meters, feet, miles, kilometers, yards, inches • Mass — grams, kilograms, pounds, ounces, stones • Temperature — Celsius, Fahrenheit, Kelvin • Volume — liters, gallons, cups, fluid ounces, milliliters • Speed — m/s, km/h, mph, knots • Area — m², ft², acres, hectares • Time, Energy, Power, Pressure, Data, Angle WHY ROSETTA IS DIFFERENT • No ads. No tracking. No accounts. No analytics SDK ships in the app. • No settings to configure. The defaults are the right defaults. • Works offline. Currency rates cache after one online fetch; everything else needs no network at all. • Two-way input — convert in either direction with a single tap. • Tap any result to copy. A quiet "Copied" toast confirms. • Light and dark mode automatic, with locale-aware number formatting and gentle haptics. Free. Forever free. Made by Optiwise.
