UnitsCR is a simple “Unit Converter” that allows You, in a really quick way, to convert common units. For example: are, acre, square foot, square kilometer, hectare, square meter, square yard, foot, inch, kilometer, meter, mile, yard, kilogram, pound, Celcius, Fahrenheit, kelvin, litre, gallon, horse power, joule, kilocalorie, watt, degree, radian, km/h, m/s, mph!

Where is its “simplicity”? There are only two steps to get conversion of one of the units mentioned above: enter value and select the unit. There is no need to select target unit. This app converts selected unit to all possible target units.

Remember, changing sign (+/-) works only with Celcius, Fahrenheit and kelvin.
