they're unitless - call them anything you like. Same with blender and
a few other modellers.

However when feeding the model to skeinforge to be printed, they'll be
interpreted as millimeters. Please note this choice of units is a
skeinforge and/or firmware decision, not openscad so you won't find
any openscad documentation about it!
