What Is This Tool?
This tool converts pressure measurements from Inch water (60°F) [inAq], a unit describing very small pressures based on water column height at 60 °F, into Ton-force (long)/square inch, a legacy Imperial unit used in historical British engineering and industrial specifications.
How to Use This Tool?
-
Enter the pressure value in Inch water (60°F) [inAq].
-
Select the target unit as Ton-force (long)/square inch.

Examples
-
10 Inch water (60°F) [inAq] converts to 0.000161123 ton-force (long)/square inch.
-
1000 Inch water (60°F) [inAq] equates to 0.0161123 ton-force (long)/square inch.
Common Use Cases
-
Measuring duct and filter pressure differences in HVAC systems.
-
Specifying low pressures for residential gas services and regulator settings.
-
Reading differential-pressure sensors in cleanroom and ventilation controls.
-
Interpreting historical British engineering specifications involving bearing or contact pressures.
-
Reviewing legacy industrial press and forging equipment capacities.
-
Converting older imperial pressure values into modern SI units for analysis or design updates.
Tips & Best Practices
-
Ensure the input pressure is measured at 60 °F to maintain accuracy for Inch water values.
-
Use this tool primarily for bridging legacy and modern pressure unit understanding.
-
Handle conversion results carefully due to the large scale difference between the units.
-
Cross-check conversions when working with critical engineering data involving legacy units.
Limitations
-
Inch water (60°F) depends on water density at a precise temperature, meaning temperature changes affect result accuracy.
-
Ton-force (long)/square inch is a legacy unit uncommon in current SI-based engineering practices.
-
Significant scale differences between Inch water and Ton-force (long)/square inch require careful numerical attention to avoid errors.
Frequently Asked Questions
-
Why is the Inch water unit specified at 60°F?
-
Inch water (60°F) is temperature-specified because the density of water changes with temperature, affecting the pressure value represented by a 1-inch water column.
-
What is a ton-force (long)/square inch used for?
-
Ton-force (long)/square inch is a legacy British unit representing pressure as the weight of one long ton over one square inch, commonly found in historical heavy machinery and industrial press specifications.
-
Can I use this conversion for modern engineering calculations?
-
This conversion is mainly useful for interpreting legacy data and bridging old and new pressure units; it is less common in modern SI-based engineering practices.
