This screen lets you convert different units of measurement
Clicking the menu items will act the same as clicking the list items
There are 6 list items in this screen that react to clicking:
Unit Type: Select which types of units to choose from (ie: Weight, Mass, Distance, Speed)
Input Unit/Output Unit: Select the unit to be converted from/to
Input Value: Lets you enter a number to be converted
Output Value: Shows the list in a message box, in case the output value is too long and cut off to fit on screen
Switch I/O Units: Switch the "Input Unit" with the "Output Unit"
If there are too many items in a dropdown menu for unit type or unit selecting, the dropdown items will be sorted into their first letter, to reduce scrolling.
