Convert Units Calculator

Convert Units Calculator is a unit converter and recipe converter with zero clutter: type a number once and read it in every unit that matters, or paste a recipe and convert every measure at once.

The conversion you asked for lands front and centre, big enough to read across the kitchen. The rest of the category is already worked out below it - a whole measurement converter on one clean screen.

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

RECIPE CONVERTER
Paste the ingredients from a recipe and every measure converts in one go: cups of flour, butter and sugar to grams, milk and oil to millilitres, ounces to grams, and the oven temperature, gas marks included, rounded to the dial. Halve, double or triple the recipe - or scale it to the servings you need - then copy or share it. Baking from a recipe in grams? It converts grams back to cups and spoons too. It reads recipes written in English, with cups, spoons and pints as US measures.

CUPS TO GRAMS, PROPERLY
A cup of flour and a cup of honey do not weigh the same, so this cooking converter asks which one. Pick from 39 ingredients - flour, granulated and brown sugar, butter, oats, nuts, raisins, coconut, cheese, honey, oils, peanut butter and more - and cups, tablespoons and teaspoons convert straight to grams and ounces. US cups, metric cups (250 mL) and Australian tablespoons (20 mL) are all here, and results come back in the fractions a measuring cup is marked in: "2 1/8", not 2.083333.

A KEYPAD BUILT FOR NUMBERS
Bigger keys than the system keyboard, always on screen, with + − × ÷: type 12*3.5 and it converts 42. Kitchen measures add 1/2, 1/3, 1/4 and 3/4 keys; feet and inches add feet and inch marks, so 5'11" is typed the way it is written.

FIND ANY UNIT
Search every unit from the header - "psi", "gibibyte", "flour" - and land on the right converter with it selected.

A unit converter that needs no connection: every conversion is computed on your device from fixed, standard factors - a mile is 1,609.344 metres, a pound is 0.45359237 kilograms. No currency tab: rates go stale, physics does not.

DARK MODE, NOTHING TO SET UP

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 unlocks 2 to 10 decimal places. Every converter, including the recipe converter, stays free.
