Please give me the procedure to solve this.
 
Convert a pressure of 1.033*10000 kgf/(m*m)into cm of mercury column.
[density=13.6g/cc & g=980 cm/(s*s)]

1 kgf=9.8N thus pressure is=10.1234 N/m*m
pressure=hdg
so, hdg=10.1234*10000(all in SI units)
h*13600*9.8=10.1234*10000
h=(10.1234*10000)/(13600*9.8)
i.e.0.759m hg
