Expert Answer:

both are gravitational force of fluid column on area of 1 square metre. Atmospheric pressure is due to air present in the atmosphere. Liquid pressure at a point is due to the weight(gravitational force ) of liquid column of cross section of one square metre area. 
the formula for pressure p is  p=ρgh, where ρ is density of air/liquid, g is acceleration due to gravity and h is height of air/liquid column.
