The I believe the Communist countries of Russia and China use metric flight
levels and have used it for many decades. How pilots adjust I don't
remember. I have heard that on some rare occasions safety problems were
encountered when crossing into their flight space.

Stan,
I lifted the following
<<
China, Mongolia, Russia and many CIS countries use flight levels specified
in metres. Aircraft entering these areas normally make a slight climb or
descent to adjust for this.
from http://en.wikipedia.org/wiki/Flight_level
I have no way of verifying it.
Regards
Martin

I was under the impression that the world flies at foot-based flight
levels.
To change to all-metric entails a massive cost of changing altimeter
measurement and display equipment and training pilots. All of these are
based on safety. New commercial planes have soft displays so it would be
less costly to change displays on them, however, the need for education
and
training still exists for pilots, many of whom are private small plane
people.
It's much like changing gasoline pumps for cars. A large percentage of
them
were mechanical-based back during the 1970s when there was a big push to
go
metric. However, virtually all pumps today have soft displays and the
pumps
fuel-measuring devices are easily switched between metric and English
units.
