What Is This Tool?
This unit converter transforms pressure values from pound-force per square inch (psi), an imperial unit used in many engineering and everyday applications, to foot water (60°F) [ftAq], which represents pressure as hydrostatic head of water at 60 degrees Fahrenheit.
How to Use This Tool?
-
Enter the pressure value in pound-force per square inch (psi).
-
Select pound-force/square inch as the input unit.
-
Choose foot water (60°F) [ftAq] as the output unit.
-
Click the convert button to see the equivalent pressure expressed in foot water (60°F).
Key Features
-
Converts psi values to foot water (60°F) pressure units
-
Browser-based and user-friendly interface
-
Supports pressure conversions relevant to HVAC, fluid mechanics, and gas regulation
-
Utilizes the specific conversion rate linking these units accurately for low-pressure contexts
Examples
-
5 psi converts to approximately 11.54 ftAq
-
0.1 psi converts to approximately 0.23 ftAq
-
Use the formula: 1 psi = 2.308938197 ftAq for manual calculations
Common Use Cases
-
Measuring and specifying low-pressure differentials in HVAC systems.
-
Assessing gas pressures in distribution and leak testing scenarios.
-
Expressing hydraulic head or pressure losses in water filtration and laboratory fluid systems.
Tips & Best Practices
-
Use this conversion when working with low-pressure applications for improved clarity.
-
Remember that foot water (60°F) relates specifically to water at 60°F under standard gravity.
-
For very high pressures, consider staying with psi as foot water units are less practical.
Limitations
-
Conversion accuracy depends on water temperature being 60°F and assumes pure water.
-
Not suitable for fluids other than water or varying temperatures which affect pressure values.
-
Foot water units are impractical for high-pressure measurements where psi is standard.
Frequently Asked Questions
-
Why use foot water (60°F) instead of psi for pressure?
-
Foot water (60°F) expresses pressure as a hydrostatic head, which is more intuitive for low-pressure fluid and gas measurements, especially in HVAC and hydraulic contexts.
Key Terminology
-
Pound-force/square inch (psi)
-
An imperial pressure unit defined as one pound-force applied per square inch of area, commonly used in engineering and automotive contexts.
-
Foot water (60°F) [ftAq]
-
A pressure unit describing the hydrostatic pressure from a 1-foot column of pure water at 60°F under standard gravity.
