I believe the conversion is 0.4mm = 1 LDU.  At least, that's what I always
use.

This is only an approximation.  The LEGO bricks are not metric -- The
dimensions are based on inches.  The width of one brick is 5/16 inch
and the height (without studs) is 6/16 inch.  So 0.39370mm = 1LDU is
more precise.

I normally try to measure LEGO elements against other LEGO bricks, to
avoid this trouble.

If anybody doubt these dimensions, they can try to measure the
dimensions of a 32x32 baseplate.  Is it closer to 10' by 10' or 25.6cm
by 25.6cm?

But 0.4mm = 1 LDU (also known as 1mm = 2.5 LDU) is for us Metrics a solid
enough basis to model parts with.

(...) For large LEGO elements, the difference would probably be significant, so I would suggest using 0.3937mm = 1LDU. But it's normally better to measure new elements along long LEGO beams, when applicable. Fredrik (24 years ago, 10-Jun-00, to lugnet.cad.dev)
