[x3d-public] [x3dom-users] Scale and relative size

has a nice soda can.

The default unit is meter and it looks like the soda can uses meter.
It does not mean that scene authors adhere to that in general. There
is a UNIT statement in X3D but it is rarely used and x3dom does not
support it. Otherwise X3D is unit agnostic, eg, the length unit in
your scene is whatever you designate and will be the same for all
coordinates. Meter or millimeter is a common choice.

Cheers, -Andreas
