UnitBox converts everything length, weight, temperature, volume, area, speed, force, pressure, and energy completely offline, with every unit unlocked from the first launch. No currency conversion, no accounts, no ads, nothing to buy. Just a fast, accurate converter that works the way a converter should. WHY UNITBOX Most unit converters get expensive right when you actually need them: scientific units like Newtons get locked behind a paywall, video ads interrupt you mid-number-entry, or a permanent unlock costs more than dinner. UnitBox has none of that. Every category including Force, Pressure, and Energy is unlocked the moment you install it. NINE CATEGORIES, EVERY UNIT • Length meters, feet, miles, kilometers, and more • Weight kilograms, pounds, ounces, grams, stone, metric tons • Temperature Celsius, Fahrenheit, Kelvin • Volume liters, milliliters, gallons, fluid ounces, cups • Area square meters, square feet, acres, hectares • Speed km/h, mph, m/s, knots • Force Newtons, pound-force • Pressure Pascals, bar, PSI, atmospheres • Energy Joules, calories, kilowatt-hours BUILT FOR SPEED Type a number, tap a unit, get your answer instantly no network required, no loading spinner, no waiting on a video before you can see your conversion. UnitBox works exactly the same on a plane, underground, or with your phone in airplane mode. PRIVATE BY DESIGN UnitBox doesn't ask for an account, doesn't send your data anywhere, and doesn't need permissions it can't justify. There's nothing to sign up for and nothing to track. Everything unlocked. Nothing to buy. Just a converter.
