FCC (Fuel Consumption Converter) is a convenient and intuitive app created for drivers and car enthusiasts who want to easily and quickly convert various fuel consumption measurements. If you're looking for a reliable fuel consumption calculator, FCC will become your indispensable assistant, especially for the most popular conversion: from miles per gallon (MPG) to liters per 100 km (l/100 km). With FCC, you can effortlessly convert between the main units of measurement: • miles per gallon (mpg) for the US • miles per gallon (mpg) for the UK • liters per 100 km (l/100 km) • kilometers per liter (km/l) • miles per liter (mi/l) The FCC app offers two data input modes to make it as accessible as possible for everyone: a standard keyboard or an innovative swipe-based input mode, which makes use even faster and more convenient. Additionally, you can customize the app to your liking, choosing from a variety of color themes, and also activate a dark mode for comfortable work at any time of day. FCC not only converts but also helps you keep track of your fuel consumption. You can save your results to a special list, which allows you to easily monitor your progress. Thanks to advanced sorting and filtering functions, you can quickly find the necessary entries and analyze your data. This is the ideal tool for those who strive for fuel economy and perform a detailed fuel consumption calculation. It is especially worth noting that the FCC-Fuel Consumption Converter app has gained popularity among owners of American cars. In the US, they use their own measurement system — miles per gallon (mpg), which can be difficult to understand in other countries where different units are used. In this case, FCC comes to the rescue, easily and quickly converting mpg (miles per gallon) into understandable units such as l/100km, km/l, and mi/l. This makes it an essential tool for travelers driving American cars abroad or for those who simply want to compare their car's efficiency. Whether you are traveling abroad or simply want to compare your car's fuel efficiency, FCC makes the process of converting and understanding the metrics as simple and clear as possible.

UnitBox converts everything length, weight, temperature, volume, area, speed, force, pressure, and energy completely offline, with every unit unlocked from the first launch. No currency conversion, no accounts, no ads, nothing to buy. Just a fast, accurate converter that works the way a converter should. WHY UNITBOX Most unit converters get expensive right when you actually need them: scientific units like Newtons get locked behind a paywall, video ads interrupt you mid-number-entry, or a permanent unlock costs more than dinner. UnitBox has none of that. Every category including Force, Pressure, and Energy is unlocked the moment you install it. NINE CATEGORIES, EVERY UNIT • Length meters, feet, miles, kilometers, and more • Weight kilograms, pounds, ounces, grams, stone, metric tons • Temperature Celsius, Fahrenheit, Kelvin • Volume liters, milliliters, gallons, fluid ounces, cups • Area square meters, square feet, acres, hectares • Speed km/h, mph, m/s, knots • Force Newtons, pound-force • Pressure Pascals, bar, PSI, atmospheres • Energy Joules, calories, kilowatt-hours BUILT FOR SPEED Type a number, tap a unit, get your answer instantly no network required, no loading spinner, no waiting on a video before you can see your conversion. UnitBox works exactly the same on a plane, underground, or with your phone in airplane mode. PRIVATE BY DESIGN UnitBox doesn't ask for an account, doesn't send your data anywhere, and doesn't need permissions it can't justify. There's nothing to sign up for and nothing to track. Everything unlocked. Nothing to buy. Just a converter.
