Bill, Jim & friends:
In my Mail to Carl - usma 26833 Metre-Lumb vs Metre stick (2003 September
04), I suggested to use and diostribute QUARTER METRE scales to children, so
the 'young minds learn and understand' the use of Le Systeme d'Unites (SI)
when their mind is unpolluted i.e. post-primary classes.
YES, QSI used the occasion in poularising among interested industries in US.

The USMA sells its own ruler at a very inexpensive price (in fact, we got
the ruler idea from the USMA), so I do not think they would want to give
ours away.
Comment on Jim Elwell's message:
I think the USMA would be happy to let everyone know that the QSI rulers
are available. I know they will publish the information in their newsletter
and I believe they would put it on the web site if asked. USMA is in the
business of promoting metric, not the business of selling rulers.
Comparison of rulers:
The USMA ruler is also a good one, and not very expensive. See the USMA web
site for details.
The USMA ruler is 200 mm long while QSI's is 250 mm long. I also have one
that is 300 mm long from the Lummus Co. All are good (except for the fact
that the Lummus one has inches in addition to metric). I've also seen 150
mm rulers.
I find that one length is sometimes better than another for different
purposes. The 200 mm USMA version is handier to carry around because of
it's smaller size. The 300 mm Lummus version is good for drawing lines that
extend for the entire length of a standard 215 mm X 280 mm page (or for
measuring the length of that page). QSI's 250 mm rule may be a good
compromise between the two. I think 150 mm rules are a bit too short for
most things.
