Good grief. Here I am about to patent and market my Reallygood Raisin
Scoop to people interested in comparative studies of the raisin content
in raisin-bran breakfast cereals and now you tell me that I've got to
mark it in SI units.
What about people who market ring gauges for jewelry? How about thread
gauges -- does that mean that all threaded fasteners now must be rated
in metric units, even non-metric fasteners? How about those measuring
sticks used by lumbermen to estimate the number of board-feet in a log?
NIST SP 811 doesn't give a conversion for "board foot" and SI 10
explicitly declines to do so, saying that the definition of a board foot
used nominal and not actual measurements.
