# Underwater Pressure

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Underwater pressure, abbreviated as $$p_u$$, is the added pressure exerted underwater directly above a spot at the water level.

## Underwater Pressure formula

 $$\large{ p_u = 1025 \; g\; d }$$

### Where:

 Units English Metric $$\large{ p_u }$$ = underwater pressure $$\large{\frac{lbf}{in^2}}$$ $$\large{Pa}$$ $$\large{ g }$$ = gravitational acceleration $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$ $$\large{ d }$$ = depth under water $$\large{ft}$$ $$\large{m}$$
