P = (density of Hg) X g X height of Hg column
P = 13.6 X 103 X (9.8) X (0.76)  
P = 1.01 X 105 N/m(This is in SI system or mks system)
Convert unit of force N int dyne.    1N = 105 dyne
Convert unit of area m2 int cm2.    1 m2 = 104 cm2
Using these two values we get the unit of Pressure in cgs unit as  1.01 X 105 X (105 dyne)/(104 cm2)
Pressue in cgs system = 1.01 X 106  dyne/cm2
