Unit Converter & Currency

Convert measurements for everyday tasks, study, work and travel. Unit Converter brings metric and imperial units, a currency converter and scientific mode together in one app. Check length, weight, temperature, area, volume and speed without working out conversion factors yourself. Need kg to lbs, cm to inches or liters to US gallons? Select the matching category and source unit to compare the values. Convert between Celsius and Fahrenheit for temperature readings. SEE A CATEGORY ON ONE SCREEN Choose a category and enter a value in the unit you know. View the other units in that category on the same screen and switch the input unit as needed. Compare several equivalent measurements without repeatedly opening a different conversion. EVERYDAY MEASUREMENTS • Length and distance: inches, feet, yards, miles, meters and kilometers. • Weight and mass: pounds, ounces, kilograms, tons and grains. • Temperature: convert temperature units for everyday reference. • Area: square feet, square inches, square meters, acres and hectares. • Volume: liters, US gallons, pints and cubic units. • Speed: miles per hour, kilometers per hour, meters and feet per second. • Cooking measures: work with spoon measures, ounces, pints and other supported kitchen units. TECHNICAL UNIT CONVERSIONS Use categories for time, force, pressure, power, fuel consumption, digital storage, angles and frequency. Radiation, radioactivity and sound level conversions are also available. Scientific mode and metric and imperial measurements help you work with values from different sources. Also convert energy, luminance, luminous intensity and illuminance. Magnetic conversions include magnetomotive force, magnetic field strength, magnetic flux and magnetic flux density; try ampere-turns, oersted, webers, tesla and gauss. CURRENCY CONVERTER Convert between supported currencies, including US dollars, euros, rubles and Japanese yen. Bitcoin conversion is also available. Unit conversions work offline; online currency features need a connection. Check the rate available in the app before comparing prices or planning a purchase. Convert 79 currencies, including EUR, USD, RUB and CNY, and 50 cryptocurrencies, including Bitcoin, Ethereum, Tether and Solana. The crypto list can refresh from the server at launch. FROM A RECIPE TO A TECHNICAL SPECIFICATION Read a dimension given in inches, compare a distance in miles and kilometers, or convert weight and volume while following a recipe. Keep the category and unit clear: a fluid ounce measures volume, while a weight ounce measures mass. Select the appropriate unit for your source measurement. The app includes color schemes and a compact interface for regular conversions. Keep a measurement converter close at hand whenever a value is expressed in unfamiliar units.
