Pressure of Column of Water - Simple Physics Homework Help?

This should be a simple problem, but for some reason the units are really confusing me.

The pressure exerted by a column of water is a product of the depth (Z), gravity (9.8 m/s^2) and the density of the water above it.

The problem asks for units in atmospheres, bar and psi.

Using the values that are provided in the homework problem - Pressure SHOULD equal:

(1025 kg/m^3)(9.8 m/s^2)(200 m) = 2009000 (unit?)

What would the units be? And how could I convert it to atm, bar and psi?
