This Universal Converter allows you to convert to and from many UK, US, JP and metric units. To do a conversion, simply select a category (length, speed, surface, temperature, volume, weight, etc.), select the source and the target units. The conversation is made on the fly as you type the source value.
You can also now do some currency conversion, display real-time time differences in two places in the world at the same time and look up country and phone codes.
The "Close to system tray" option allows you to run a single instance of the program and to automatically minimize it to the system tray (the part of the taskbar near the clock) when you close it. If you need the program again, simply double-click its icon in the system tray.
