Convert Units Calculator

Convert Units Calculator is a unit converter with zero clutter: type a number once and read it in every unit that matters.

The conversion you asked for lands front and center, big enough to read from across the desk. The rest of the category is already worked out in the list right below it — so when one answer raises the next question, it's on screen before you ask.

Kilometers to miles, kg to lbs, Celsius to Fahrenheit, cups to mL, mph to km/h, GB to MB — the conversions you actually reach for, in one clean screen.

EVERY UNIT, ONE TAP
- Results update on every keystroke — there is no Convert button
- Swap flips the direction in one tap
- Tap the big result, or any row in the list, to copy it
- Commas welcome: "1,609.344" parses just like 1609.344
- Extreme results switch to scientific notation instead of rounding to zero

WORKS OFFLINE
Every conversion is computed on your device from fixed, standard factors — 1 mile is 1,609.344 meters, 1 pound is 0.45359237 kilograms. No connection needed, ever. (That's also why there's no currency tab: exchange rates go stale, physics doesn't.)

DARK MODE
The app follows your system appearance automatically — a clean light theme by day, deep navy at night.

NOTHING TO SET UP
No account, no sign-in, no onboarding tour. Open it, type, copy, done.

ABOUT ADS
The app is free and shows a small banner ad via Google AdMob to keep it that way. No in-app purchases, no subscriptions, no locked features.
