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 centre, big enough to read across the desk. The rest of the category is already worked out below it - so when one answer raises the next question, it is on screen before you ask.

Kilometres to miles, kg to lbs, Celsius to Fahrenheit, cups to grams, mpg to L/100km, GB to GiB, psi to bar - the conversions you actually reach for, on one clean screen.

CUPS TO GRAMS, PROPERLY
A cup of flour and a cup of honey do not weigh the same, so the Cooking category asks which one. Pick from 26 ingredients - flour, granulated and brown sugar, butter, oats, rice, honey, oils, peanut butter and the rest - and cups, tablespoons and teaspoons convert straight to grams and ounces. The weight per cup is shown on screen, so you can check it yourself.

Recipes are written in fractions, so the app reads and writes them: type "1 1/2" or "1½" cups, and 250 g of flour comes back as 2.083333 cups and "2 1/8" - the nearest mark on a real one.

A KEYPAD BUILT FOR NUMBERS
The system keyboard covers half the screen and has no operators. The built-in keypad stays put, has bigger keys, and adds + - x /. Type 12*3.5 into the value field and the converter works on the answer. Prefer your own? Turn the keypad off in Settings.

FIND ANY UNIT
Search every unit in the app from the header - type "psi" or "gibibyte" and the converter takes you to the right category with the unit selected. Ingredients are in there too: type "flour" and you land on the cooking screen with flour chosen.

EVERYTHING IS LIVE
- Results update on every keystroke. There is no Convert button.
- Swap flips the direction in one tap.
- Tap the big result, or any row below it, to copy it.
- Pin the conversions you reach for; they sit one tap away.
- The app reopens on the conversion you used last.
- Commas welcome: "1,609.344" and "1.609,344" both read as 1609.344.
- Feet-and-inches shorthand: type 5'11" when converting from feet.

WORKS OFFLINE, ALWAYS
Every conversion is computed on your device from fixed, standard factors - a mile is 1,609.344 metres, a pound is 0.45359237 kilograms. That is also why there is no currency tab: rates go stale, physics does not.

DARK MODE
Follows your system appearance - light by day, deep navy at night - or lock it to one in Settings.

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

FREE, WITH ONE OPTIONAL UPGRADE
The app is free and shows a single banner ad. Convert Pro is a one-time purchase - not a subscription - that removes the ad, lifts the cap on pinned conversions, and lets you pick 2 to 10 decimal places. Every category and every unit stays free.
