Hydrostatic Pressure Calculator
💨 Gas Laws & Fluids. Use the Hydrostatic pressure formula to find pressure, density ρ, depth: pick the value you want, type the others, and the answer updates as you go.
Pressure98100 Pa
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Pressure | Pa |
| Density ρ | kg/m³ |
| Depth | m |
Worked example
Find the pressure when Density ρ = 1000 kg/m³, Depth = 10 m.
Using P = ρ g h: Pressure = 98100 Pa.
Frequently asked questions
What is the formula for Hydrostatic pressure?
P = ρ g h.
What do the letters stand for, and what units are used?
Pressure in Pa, Density ρ in kg/m³, Depth in m.
How do you calculate pressure?
Put the values into P = ρ g h. For example, with Density ρ = 1000 kg/m³, Depth = 10 m, pressure = 98100 Pa.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (pressure, density ρ, depth) and fill in the others: it rearranges the formula for you.
