What Is This Tool?
This converter allows you to change pressure measurements from psi, a common Imperial/US unit, to ton-force (long)/square inch, an older British unit expressing pressure as force per unit area.
How to Use This Tool?
-
Enter the pressure value in psi that you wish to convert.
-
Select psi as the input unit and ton-force (long)/square inch as the output unit.
-
Click convert to obtain the equivalent pressure in ton-force (long)/square inch.
-
Use the result to interpret or compare pressure data in legacy engineering contexts.
Key Features
-
Converts pressure values from psi to ton-force (long)/square inch
-
Based on established conversion rate: 1 psi = 0.0004464286 ton-force (long)/square inch
-
Supports understanding of legacy British engineering pressure units
-
Useful for updating historical designs or analyzing industrial machinery pressures
Examples
-
100 psi converts to 0.04464286 ton-force (long)/square inch.
-
500 psi equals 0.2232143 ton-force (long)/square inch.
Common Use Cases
-
Interpreting pressure values from older British engineering documents.
-
Converting legacy pressure units for heavy machinery and ship fittings.
-
Updating designs or analyses with pressure given in long tons per square inch.
-
Rating industrial press and forging equipment pressures in historical terms.
Tips & Best Practices
-
Verify unit definitions especially when dealing with regional variations of the long ton.
-
Be cautious when applying this conversion in modern engineering due to legacy status of the unit.
-
Reference context-specific standards to confirm precision requirements.
-
Use this conversion to bridge legacy imperial units with SI units during updates.
Limitations
-
Ton-force (long)/square inch is a legacy unit not typically used in current standards.
-
Precision may differ when converting between imperial and legacy units; confirm with standards.
-
Regional differences in ton definitions can affect conversion accuracy.
-
This converter assumes imperial pound-force and long ton definitions.
Frequently Asked Questions
-
What does psi measure?

Psi [psi]
-
A pressure unit representing one pound-force applied to one square inch, used in Imperial/US customary systems.
-
Ton-force (long)/square inch
-
A legacy unit expressing pressure as force of one long ton distributed over one square inch; one long ton equals 2240 pounds.
-
Conversion Rate
