Convert Units for Free
iTunes link: Convert Units for Free - £Free
The iPhone isn’t exactly short of applications to convert between different units, but some of these are paid for apps and many are limited to specific types of conversions. Convert Units beats the lot because it’s free and allows you to convert between a very broad range of different units including everything from time and volume, to speed and temperatures.
The user interface is refreshingly straightforward. You simply select the type of conversion you want to perform using the button in the centre of the display and then use two roller deck menus at the top to choose the two units to convert between. There’s a keypad at the bottom of the display where you enter the amounts that you want to convert.
Convert Units’ broad range of conversion options and slick, easy to use interface makes it a worthwhile app to have on your phone.
