"U need a Unit"
Converter for Half-Life, Quake, Doom and Wolf 3D. There centimeters, meters, inches (aka, units for Half-Life and CS), and the initial units of the id Softaware, for Quake, Doom and Wolf (there stature 56 units instead of 72 in HL). Nunits is my personal units, they are obtained by dividing my height growth player in HL, in order to build the world in the Hummer, the camera/FOV and customize the player on the basis of physics itself :)
