UnitConverter: Units & GPS

Unit Converter turns everyday measurements into the unit you need as you type, and adds a set of handy location tools. Convert a recipe, a distance, a temperature or a file size, then look up a place or read your current coordinates.

• Convert length, weight, area, volume, cooking, temperature, speed, time, data, pressure, energy and fuel economy
• Pick from over 100 units in a searchable list, star your favorites and swap units with one tap
• Keep US, imperial and metric apart: US and UK gallons, short and long tons, two kinds of calorie, kB and KiB, bits and bytes
• Temperature in Celsius, Fahrenheit, Kelvin and Rankine, with an absolute-zero check and a temperature-difference mode
• See related units at once, copy the result and save the conversions you use often
• Convert coordinates between decimal degrees, degrees-minutes-seconds and UTM
• Search for places and addresses, save favorites and revisit recent searches
• See your current position on a map with its accuracy, and copy the coordinates
• Find the address of any coordinates, the antipode of a point, the distance and bearing between two points, or random points

Conversion factors follow NIST SP 811 and the SI Brochure.
