Convert Units Calculator

Features
Read full description

Type a number once and read it in every unit that matters - or paste a whole 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, so the next question is answered before you ask it. Kilometres to miles, kg to lbs, Celsius to Fahrenheit, cups to grams, mpg to L/100km, GB to GiB, psi to bar. No account, no sign-in, no connection. A 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 mark on the dial. Halve it, double it, triple it or scale it to the servings you need, then copy it or share it. It works the other way too: grams back to cups and spoons. Anything it has no cup weight for stays in spoons or millilitres - never a guessed weight. 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 the Cooking category asks which one. Choose from 39 ingredients - all-purpose and bread flour, granulated, brown and powdered sugar, butter, cocoa, oats, nuts, raisins, coconut, cheese, honey, molasses, oils, peanut butter and the rest. The weight per cup is shown on screen, so you can check it against your own reference. 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: 250 g of flour is 2.083333 cups - or "2 1/8". A KEYPAD BUILT FOR NUMBERS Bigger keys than the system keyboard, always on screen, with + βˆ’ Γ— Γ·: type 12*3.5 and it converts 42. Cups and spoons add Β½ β…“ ΒΌ ΒΎ keys, so 1Β½ cups is two taps. Feet and inches add feet and inch marks, so a height is typed the way it is written: 5'11". Prefer your own keyboard? Turn the keypad off in Settings. FIND ANY UNIT Search every unit from the header - "psi", "gibibyte", "cups" - and land in the right category with the unit selected. Type an ingredient, like "flour", and land on the cooking screen with it 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, to copy it. Share sends the whole conversion, written out. - Pin the conversions you reach for; they sit one tap away. - The app reopens on the conversion you used last. - "1,609.344" and "1.609,344" both read as 1609.344. 19 CATEGORIES, 142 UNITS Cooking, length, weight, temperature, volume, area, speed, time, digital storage, energy, pressure, fuel economy, power, angle, frequency, force, torque, density and bandwidth - including the ones other converters skip: gibibytes as well as gigabytes, UK gallons as well as US, L/100km as well as mpg, metric horsepower as well as mechanical, plus Rankine, Mach, knots, carats and nautical miles. 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, NOTHING TO SET UP Follows your system appearance, or lock it to light or dark in Settings. No account, no sign-in, no onboarding tour. Open it, type, 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 choose 2 to 10 decimal places. Every category, every unit and the recipe converter stay free. Privacy policy: https://convert.chinesepowered.com/privacy.html
