Units of hydrostatic pressure?

Can anyone tell me why the formula for hydrostatic pressure = density of fluid x depth in the fluid x acceleration due to gravity= ρgh, does not workout to have the units of N/m² or Pa? When I try to work out the units, it is:  kg/m³   x  m/s²    x   m   =  kg/ms² ?

Look at it this way.

Density times height equals mass/area. Multiplying this with acceleration gives force, which is acting on unit area. Force/area is pressure.
