what is the unit for the Three js objects?

Question

var camera = new THREE.PerspectiveCamera(
    35,         // Field of view
    800 / 640,  // Aspect ratio
    .1,         // Near
    10000       // Far
);

var cube = new THREE.Mesh(
    new THREE.CubeGeometry( 5, 5, 5 ),
    new THREE.MeshLambertMaterial( { color: 0xFF0000 } )
);

In camera, what is the unit for Near and Far parameters.

In Cube what is the unit of the parameters for CubeGeometry

Please point me to the url where, i can find details about

Object space - (the local axis used to draw an object) World space - (the global axis)

The official answer is that ThreeJS uses SI units for all measures, see here:
