    Standard atmosphere (symbol: atm) is a unit of pressure. Standard atmosphere is a non-SI unit that is internationally recognized. The 10th Conférence Générale des Poids et Mesures (10th CGPM) adopted standard atmosphere for general use and affirmed its definition of being precisely equal to 1,013,250 dynes per cm2 (101,325 Pa). This value is intended to represent the mean atmospheric pressure at mean sea level at the latitude of Paris, France, and as a practical matter, truly reflects the mean sea level pressure for many of the industrialized nations (those with latitudes similar to Paris).

    A pressure of 1 atm can also be stated as:

    ≡1.013 25 bar

    ≡101.325 kPa

    ≡1013.25 millibars (mbar, also mb) or hectopascals (hPa)

    ≡760 torr

    "ATM" refers to 'atmosphere'. Probably in reference to pressure.....'atmospheric pressure'.
