External Hydrostatic Pressure Calculator

Calculate External Hydrostatic Pressure

kg/m³
Density of the fluid (e.g., freshwater ≈ 1000 kg/m³, seawater ≈ 1025 kg/m³).
m
The depth of the object or point below the fluid surface.
m/s²
Acceleration due to gravity (approx. 9.80665 m/s² on Earth).

External Hydrostatic Pressure (P): Pascals (Pa)

Easily calculate external hydrostatic pressure exerted by fluids on submerged objects or structures. This essential tool helps engineers, marine architects, and designers ensure structural integrity by accurately determining the forces acting on components under water or other liquids. Simply input fluid density, depth, and gravitational acceleration.

Formula:

The formula for external hydrostatic pressure is:

P = ρgh

  • P = External Hydrostatic Pressure (Pascals - Pa)
  • ρ = Fluid Density (kilograms per cubic meter - kg/m3)
  • g = Gravitational Acceleration (meters per second squared - m/s2)
  • h = Depth of Fluid (meters - m)
