What Is This Tool?
This tool converts pressure measurements from ton-force (long) per square foot, an imperial unit used mainly in heavy industry and engineering, to foot water (60°F) [ftAq], a hydrostatic pressure unit commonly applied in HVAC and fluid mechanics.
How to Use This Tool?
-
Enter the pressure value measured in ton-force (long) per square foot into the input field
-
Select foot water (60°F) [ftAq] as the target pressure unit
-
Click the convert button to see the equivalent pressure expressed in foot water (60°F) [ftAq]
-
Use the result for HVAC, fluid mechanics, or engineering calculations
Key Features
-
Converts ton-force (long)/square foot to foot water (60°F) [ftAq] with a direct formula
-
Handles pressure units used in shipbuilding, civil engineering, and fluid dynamics
-
Supports applications in both historical imperial systems and modern hydrostatic measurements
-
Browser-based, easy-to-use interface for quick and accurate conversion
Examples
-
2 Ton-force (long)/square foot converts to approximately 71.83363 Foot water (60°F) [ftAq]
-
0.5 Ton-force (long)/square foot converts to approximately 17.95841 Foot water (60°F) [ftAq]
Common Use Cases
-
Estimating foundation bearing pressures in older imperial engineering documents
-
Specifying deck load capacities in shipbuilding and heavy industry settings
-
Measuring low-pressure differentials and draft in HVAC systems
-
Expressing hydraulic head pressures in water treatment and laboratory applications
Tips & Best Practices
-
Always verify the temperature standard (60°F) when using foot water (60°F) pressure to ensure accurate interpretation
-
Use this tool to translate legacy imperial pressure units into modern hydrostatic units for better interoperability
-
Consider the application context when converting, as ton-force (long)/square foot is suited for heavy loads, while foot water (60°F) [ftAq] fits fluid pressure scenarios
Limitations
-
Ton-force (long)/square foot is tied to imperial units, making it less suitable for very low-pressure fluid measurements without conversion
-
Foot water (60°F) [ftAq] assumes a specific temperature and standard gravity, which can affect precision if conditions vary
Frequently Asked Questions
-
What does one ton-force (long) per square foot represent?
-
It represents a pressure equivalent to one long ton-force applied over one square foot, specifically 2240 pounds-force per square foot.
-
Why use foot water (60°F) [ftAq] for pressure measurements?
-
Because it expresses hydrostatic pressure from a one-foot column of water at 60°F, making it useful for low-pressure and fluid-related readings.
-
Can I convert ton-force (long)/square foot directly to pascals?
-
Yes, one ton-force (long)/square foot is approximately equal to 1.07252×10^5 pascals.
