Virtual scale and Unity

Using a computer graphic engine, such as Unity and other 3D design applications, we work on 3D objects defined by x, y, z coordinates in a virtual three-dimensional space. There are many ways to digitally represent objects. Unity prefers a set of points connected to form a mesh of triangular faces. These faces are rendered with texture maps, lighting, and shaders to provide ever increasing degrees of realism and simulation of physical properties.

The default unit in Unity is meters. This is somewhat arbitrary. Your application can choose to allow one unit to be another measure, such as inches or kilometers. But unless really needed, it is recommended to stick with the 1 meter units (other parts of Unity assume this ...
