> 1 LDU = .397 mm
I was wondering about this number in that otherwise very
explanatory and very clear figure when I saw it in the
Brickfest presentation. I would strongly argue that Lego,
being a Danish creation, is in fact metric by design,
and that 1 LDU is actually *exactly* 0.4 mm.
Isn't that what should be stated in this important,
semi-official standards defining document?
0.4 mm happens to be quite close to 1/64 inch, but
it's clearly different enough to matter.
An accurate metric caliper just told me that to within
an accuracy of a tenth of a millimeter, 16 stud spacings
on a baseplate measure 128 mm, definitely not 5" = 127 mm,
which would be the distance if 1 LDU = 1/64". I thus have
empiric data to support my case. :)
