Water Pressure Calculator
Calculate static water pressure from head height.
How It Works
Pressure (psi) = Fluid density × Head height ÷ 144. Water: ~0.433 psi per ft.
Example
A 10 ft water column produces about 4.33 psi.
Frequently Asked Questions
What is static pressure?
The pressure from the weight of the water column alone, without any pump or flow.
How much does a foot of water weigh in psi?
Fresh water adds about 0.433 psi for every foot of head.
Can I leave density blank?
Yes — it defaults to fresh water at 62.4 lb/ft³.
