Atmospheric pressure trivia.
Jan. 15th, 2022 07:15 pmIt is a source of annoyance that nominal atmospheric pressure at sea level in metric units is about 101 kPa, or 1.01 bar in informal metric units, rather than being equal to a nice round "one bar".
However, today I discovered that -- making allowances for imprecision of topographical maps of Paris and of interpolating on atmosphere-vs-altitude charts -- the nominal atmospheric pressure at the International Bureau of Weights and Measures in Paris is, in fact 100 kPa to at least three digits of precision.
