This is a simple program I made that converts Doom Map Units to Hammer Units (Source Engine), and vice versa. It was meant to automate the calculations I was having to repeatedly punch into my calculator while working on my full conversion of Myhouse.wad.
All you do is select your conversion, enter the number of units, and then hit "Convert!" The program does the rest for you.
Unit values and conversions are as follows: 1 Doom Map unit = 1.2 inches (derived from the Doom Wiki stating that 32 map units are roughly equal to 1 meter)
1 Hammer Unit = 0.75 inches (derived from the Valve Developer Wiki stating that 16 Hammer Units is typically equal to 1 foot)
h=d/0.625 and d=h*0.625 (From calculations I did myself)
