This is an FFU Ruler but has the *mm facility to read Metric length units; the 1/8th, 1/16th & 1/32th markers speak of the SOOT measure - that I referred in my previous mails that make 8, 16, 32 to ONE Inch. The 1/10th markers show 10 marks to the Inch*.
This is sort of old Foot Rule that I used in my engineering drawing during late fifties/early sixtits, while India was in the process of converting to SI. If such scales be allowed to student community in US today; rest assured USA cannot GO METRIC in the next 100 years. I say this on the basis since US were among the 'first signatories' to Metre Convention BUT is still struggling to get out of its grip.
REMOVE INCHES and adopt METRE New (m'): '1/10^5th of ONE degree' and define Nautical Kilometre as bonus.

That's a very broad question, because there are so many kinds of rulers.
I have a Canadian steel ruler from the early 1970s with two scales on each of two sides. On one side, one edge is graduated in 5/32" units, with the other edge in inches, subdivided into 1/6 and 1/12. The inches themselves have two markings -- 1, 2, 3, 4, etc. and 6, 12, 18, 24, etc.
On the other side, one edge has inches in 1/10, with each 1/10 individually marked from 1 to 150. The other edge has inches with 1/4", 1/8", 1/16" and 1/32" subdivisions. The inches themselves are marked 1, 2, 3, 4, etc. and 150, 300, 450, 600, etc.
The ruler has other features I won't mention yet.
I want to see who can guess what kind of ruler it is, what some of the numbers mean, and what the other features might be. One clue is that, in spite of having no metric units whatever on it, it is still useful and the units (and features) still have a valid purpose.

I forgot to ask this question in my last posting. Does anyone know how long rulers have been double sided in the States? They have been double sided in Canada for many years. Doreen was teling me that when she was in grade school in the fifty's she remembers rulers with cm as well as inches. Thanks.
