If the meter had been a bit more accurate and if decimal angular
measures directly related to the meter had been accepted, the metric
system would have been better for land mensuration (surveying).  It's
very convenient that the nautical mile is close to one minute of arc
(11 parts in a thousand).

In the U.S., all surveys are in the English system and degrees-
minutes-seconds.  This may be the main impediment to the U.S.
adopting the metric system, along, perhaps, with binary fractions of
inches being convenient for carpenters (1/2, 1/4, 1/8, etc).  It
certainly would be nice for mechanics were the metric system adopted
as it would halve the size of their wrench collections.
