Atmosphere (unit)
The standard atmosphere (symbol: atm) is an international reference pressure defined as 101.325 kPa and formerly used as unit of pressure. For practical purposes it has been replaced by the bar which is 100 kPa. The difference of about 1% is not significant for many applications, and is within the error range of common pressure gauges.

Famous quotes containing the word atmosphere:
“We must be generously willing to leave for a time the narrow boundaries in which our individual lives are passed ... In this fresh, breezy atmosphere ... we will be surprised to find that many of our familiar old conventional truths look very queer indeed in some of the sudden side lights thrown upon them.”
—Bertha Honore Potter Palmer (1849–1918)
