I'll look to see if Lowe's has a stack of those "pica" or "printers"
rulers handy near the miter saw that I purchased. Grin.
Yeh, I used to have one of those rulers, too.

Some measuring devices do indeed allow one to measure in 1/6 inch
increments. However, they're almost all metal rulers, used in forms design
and once provided free by forms salespeople. I have one that I've had for
years. The minimum increment on that side of the ruler is 1/12 inch.
Because document line spacing, even in metric countries, is measured in 1/12
inch increments -- 2 increments for single space, 3 for 1½ spaces, and 4 for
double space -- the damn thing persists, and will as long as impact printers
(including typewriters) continue to exist.
Oh well.
By the way, I now use my metal ruler to hold multiple sheets of paper down,
right up against the blade of my paper cutter, to avoid having the cut go
askew. There's a use for a lot of obsolete things -- like using old
stepper-motor disk drives as door stops. (I don't do that, not even having
seen one for over 20 years.)

Subject: [USMA:40728] Miter saw
I purchased a Hitachi Compound Miter Saw (model C 10FCH2) a couple of days
ago and I'm in the process of setting it up. The directions include the
spacing of mounting holes to use in fastening the saw to a workbench. The
spacing for the holes is given in "customary" units with metric indications
in parentheses. Likewise, the hole sizes which are specified as 11/32" (9
mm). The mounting bolts are specified as 5/16" or
8 mm.
I grinned when I saw that one of the spacings was given as
14-1/6" (360 mm)
and I wondered just how many Americans have an inch tape graduated in sixths
of an inch, not to mention an 11/32 inch drill bit. By back-conversion from
360 mm it seems that Hitachi indeed intended to state fourteen and one-sixth
of an inch as the customary-unit equivalent. Sure makes metric look easier!
One dimension is missing from their drawing though--the size of the
left-right staggered offset between the two rows of holes, front and back.
So folks will end up just using the saw itself as the template, as I will.
