Water Pressure at Depth Calculator

Find fluid pressure at a given depth.

Fluid density (kg/m³)

Depth

Gravity (m/s²)

Calculated Output

Gauge pressure (Pa) 98,100

Pressure (atm) 0.9682

Formula: P = ρ · g · h

Step-by-Step Breakdown

1. Values used:

2. Fluid density = 1,000 kg/m³

3. Depth = 10

4. Gravity = 9.81 m/s²

6. Gauge pressure = Fluid density x Depth x Gravity = 1,000 x 10 x 9.81 = 98,100Pa

7. Pressure = 0.9682atm

The math behind it

gauge pressure = density × g × depth. Add atmospheric pressure for absolute.

10 m of water → 98,100 Pa (~0.97 atm).

Every 10 m of water?

Adds roughly 1 atmosphere of pressure.
