Pressure is defined as **force *per* unit area*** exerted by a fluid. Pressure is defined as **force *per* unit area*** exerted by a fluid.
$$ p = \frac{F (N)}{A(m^2)} $$ $$ p = \frac{F (N)}{A(m^2)} $$
The SI unit for pressure is called a pascal, and it's $\frac{N}{m^2}$. The SI unit for pressure is called a pascal ($Pa$), equal to $\frac{N}{m^2}$.
Pressure is exerted on the fluid's container.
Pressure is the same everywhere at the same depth.
$$ 1atm = 101.3 kPa = 14.7 psi $$
