Dear Victor,
Do you know if the DOTs attempted to go metric using centimetres?
This web page — http://www.tfhrc.gov/pubrds/summer95/p95su14.htm —
indirectly suggests that the Federal Highway Administration intends to
use centimetres as they approach metrication. This is in their first
sentence. I suspect that the guillotine, being a precision instrument
of the 1790s would almost certainly been engineered to within a
millimetre — especially for the blade.
As you probably know, I have yet to see, or hear of, a successful
metrication transition using centimetres.
See http://www.metricationmatters.com/docs/
centimetresORmillimetres.pdf for a long discussion of this issue.
Cheers,
