The conversion of angular measurements with one click. Having the ability to convert quickly and easily an angular measurement with this small utility is now possible. The interface is simple and quick and angular measurement of the four options are: sessagesimal (DEG) proximate (Grad or Gon) radiation (Rad) The automatic conversion of all four options is very convenient. In fact , it' s sufficient to complete the starting field of angular measurement, which can be either one of the four potential to achieve the completion of all fields simultaneously. We have implemented a real-time monitoring for errors in filling in the fields. The software is a stand-alone that is not necessary to install and also, thanks to its small size, it is possible its use on a portable mass storage device like a USB stick.
