No kidding! Some old metric units WERE customary! This area, like the
field of electromagnetism, were metric from the start.
I assert that "customary" does not mean "non-metric". It refers to units
that were customarily used prior to being replaced by SI units.

The article gives false information. It claims that older metric units,
like rem, rad, roentgen & curie are US customary units and sievert &
gray are SI units. Some of the commentors corrected this error, but I'm
sure that there are more people than just this author who think that
these older metric units are customary. Just like calorie is assumed by
many to be non-metric.

Excellent exposition on the subject! It's nice to see something like
this in the public media.

Id put my money on the sun and solar energy. What a source of power! I
hope we dont have to wait til oil and coal run out before we tackle
that. I wish I had a few more years left. -- Thomas Edison♽☯♑
