Paul:  The term "U.S. Customary" is the Term by which U.S. Weights and
Measures are refered to in our "Legalese".  I have seen it both capitalized
and not in BOTH legal and regulatory documents.  Take your pick.  There are
two systems of measurement recognized by U.S. Law.  For Example, check out:

http://ts.nist.gov/ts/htdocs/230/235/h130-03/04_III_Weightlaw.pdf
as adopted by the National Conference on Weights and Measures. page 22.

The   International  System  of  Units  (SI)[  NOTE 2, see page 22] and the
system  of  weights  and measures in customary use in the United States are
jointly  recognized,  and either one or both of these systems shall be used
for  all  commercial  pur-poses  in  the State.   The defini-tions of basic
units of weight and meas-ure, the tables of weight and measure, and weights
and  measures  equivalents  as  pub-lished  by  the  National  Institute of
Standards  and  Technology  are  recognized  and  shall govern weighing and
meas-uring equipment and transactions in the State.
(Amended 1993)

NOTE  2:   The  "International System of Units" means the modernized metric
system  as  established  in  1960  by the General Conference on Weights and
Measures and interpreted or modified for the United States by the Secretary
of Commerce.  [See Metric Conversion Act of 1975 (Public Law 94-168, § 3(1)
and  §  4(4),  and  NIST  Special  Publication  814  -   Metric  System  of
Measurement;  Interpretation  of  the International System of Units for the
United   States,  or  the  Federal  Register  of  December  20,  1990,  (FR
90-21913).]  (Added 1993)


This and other stuff is there in the Weights and Measures Division of the
National Institute of Standards and Technology.

Sorry to be a pedantic historian here I have to deal with medieval
customary mesures on a reguar basis and occasionally with areas where
measurements could be French, Flemish, Spanish or Austrian but surely US
measurements are not customary any more than Imperial but laid down in law.
The point with customary meausrements is they they were by the custom of
the town, region, manor, ethnic group  etc. not by statute.
