What does psi stand for?

Psi means pound-force per square inch, a pressure unit measuring force on an area of one square inch used mainly in Imperial and US customary systems.

When should I use foot water (60°F) units?

Foot water (60°F) is used for low-pressure hydrostatic or head-related measurements, common in HVAC, water filtration, and laboratory settings.

Can I convert any psi value directly to foot water (60°F)?

Yes, applying the conversion formula works for any psi value, but consider that foot water units are temperature-sensitive and suited for low pressures.

What Is This Tool?

This unit converter allows you to transform pressure measurements from psi, commonly used in automotive and hydraulic systems, to foot water (60°F), a hydrostatic pressure unit based on water column height at 60 degrees Fahrenheit.

How to Use This Tool?

Enter the pressure value measured in psi
Select psi as the input unit and foot water (60°F) as the output unit
Click convert to get the equivalent pressure in foot water (60°F)

Key Features

Converts psi to foot water (60°F) pressure units accurately
Browser-based and easy to use without installation
Supports pressure units used in mechanical, automotive, and HVAC fields

Examples

10 psi equals 23.08938197 foot water (60°F)
5 psi converts to 11.544690985 foot water (60°F)

Common Use Cases

Converting automotive tire and hydraulic system pressures from psi to water column units
Measuring low-pressure differentials in HVAC ventilation and duct diagnostics
Expressing hydraulic head or pressure drops in water filters and laboratory manometer readings

Tips & Best Practices

Use this converter for translating high-pressure psi units to low-pressure hydrostatic measurements
Verify your temperature conditions since foot water units depend on water density at 60°F
Apply conversions for accurate diagnostics in fluid and gas pressure systems

Limitations

Foot water (60°F) measurement depends on water density at a fixed temperature, so values may vary with temperature changes
Psi is better suited for high-pressure ranges, whereas foot water is ideal for low-pressure applications
Conversion accuracy can be affected if conditions deviate from standard gravity or water temperature

Key Terminology

Psi [psi]: A pressure unit defined as one pound-force applied to an area of one square inch, used mainly in Imperial and US customary systems.
Foot water (60°F) [ftAq]: A pressure unit representing hydrostatic pressure from a one-foot column of water at 60°F under standard gravity.
Hydrostatic Pressure: Pressure exerted by a fluid at rest due to the force of gravity, often measured by the height of a fluid column.
