1 micron (u) Hg	= 0.001 mm Hg = 10-3 mm Hg
1 millitorr	= 1 micron (u) Hg = 0.01 mm Hg
1 millibar (international)	= 0.75 mm Hg
1 bar (international)	= 106 dyne /cm2 - 29.53 inches Hg
1 barye	= 1 dyne/ cm2
1 newton/m2 (pascal)	= 10 dyne/ cm2 = 7.5x10-3 torr
1 newton/m2 (pascal)	= 7.5 millitorr = 7.5 micron
1 millimeter Hg	= 1000 microns = 10-3 microns = 1 torr
1 millimeter Hg	=1.333 millibar = 133.3 newton /m2
1 millimeter Hg	= 0.03937 inches Hg = 0.01934 psi
1 torr	= 1 mm Hg = 133.3 newton/m2
1 atmosphere	= 760 torr = 14.7 psi
1 psi	= 2.036 inches Hg @ 32°F = 51.72 torr
1 psi	= 2.041 inches Hg @ 58.4°F
1 inch Hg @ 32°F	= 0.4912 psi
29.921 in Hg @ 32°F	= 14.696 psi = 760 torr
30.00 in Hg @ 58.4°F	= 14.696 psi = 760 torr
