The app converts weight, length, area, volume, speed, fuel efficiency and temperature values from MKS (international) units to US customary units, such as lb, oz, ft, in, ac, mph, mile per gallon and degree Fahrenheit. Conversely, if you enter US units, the results will be in MKS values.
You can convert currency values with real time exchange rates.
Comparing price between two different countries got extremely easy with this app. To compare gas prices, for example, you just enter:
13.85 Mexican Peso / L
and the app returns
3.57 USD / gal
or most accurate price using the most recent exchange rate automatically.
