Unitly - Converter

250+ units across 25 categories, converted instantly as you type. Works entirely offline — no account, no tracking, nothing leaves your device.

Unitly turns any measurement into any other — instantly, beautifully and completely offline.

Type a value and every conversion in that category updates live as you type. No "convert" button, no waiting, no ads interrupting you.

WHAT YOU GET

• 25 categories and more than 250 units • Live results while typing — see every unit at once, not just one • One-tap copy on any result • Instant swap between your source and target unit • Search across every unit and category at once • Favorites and recent conversions, always a tap away • Designed for iPhone and iPad, in light and dark mode

EVERYDAY CATEGORIES Length, Weight & Mass, Temperature, Area, Volume, Speed, Time, Cooking, Data Storage, Digital Speed, Angle, Fuel Consumption, Typography and Astronomy.

FOR PROFESSIONALS Pressure, Energy, Power, Force, Torque, Density and Frequency — with the units engineers actually need: psi, bar, torr, mmHg, ksi, BTU, therm, kWh, hp and PS, kip, poundal, slug, lbf·ft, kgf·m and many more.

BUILT FOR REAL USE • Cooking converts US, UK and metric cups, spoons and ounces — because a "cup" is not one thing • Data Storage shows decimal (kB, MB, GB) and binary (KiB, MiB, GiB) side by side, so you can finally see why a 1 TB drive shows up as 931 GiB • Fuel Consumption handles L/100 km, km/L and both US and UK mpg • Temperature covers Celsius, Fahrenheit, Kelvin, Rankine, Réaumur and more

YOUR SETTINGS, YOUR WAY Choose Metric, Imperial (US), UK or Mixed and Unitly reorders units to match how you think — without ever hiding anything. Set decimal precision, thousands separators, scientific notation, a default unit per category, your theme and your language.

COMPLETELY OFFLINE, COMPLETELY PRIVATE Unitly makes no network requests at all. There is no account, no analytics, no advertising and no third-party SDK. Nothing you type is collected, transmitted or stored anywhere but your own device. It works the same on a plane, in a basement or on a mountain.
