Answer:
The SI unit of pressure is Pascal.
Realtion of Pascal with Atmospheric Presseure》》
1 pascal = 10 dyne/cm^2= 0.01 mbar. 1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi.
The prefix "kilo" means "1,000", so one kilopascal = 1,000 Pa.
Therefore, 101.325 kPa = 1 atm = 760 torr and 100 kPa = 1 bar = 750 torr.
