You where right and I was wrong: 1 Bar = 0.987 atmospheres (so much for
my PhD in physics). The problem is one of metric vs. non-metric worlds.
One Bar is 10**6 dyne/cm**2. It is used by the metric world as the
standard pressure at sea level. One atmosphere is also defined as the
standard pressure at sea level. Well we'll just have to wait ans sea.
