#pressure notes

Pascal -- 1 Pa = 1 N/m^2 -- 101,325 Pa = 1 atm

Atmosphere -- 1 atm = 101,325 Pa -- 1 atm = 760 mm Hg -- 1 atm = 29.92 in. Hg -- 1 atm = 14.7 psi

Millimeter of Mercury -- 760 mm Hg = 1 atm -- 1 mm Hg = 1 torr

Torr -- 1 torr = 1 mm Hg

Pounds Per Square Inch -- 1 atm = 14.7 psi

Inches of Mercury -- 1 atm = 29.92 in. Hg
