What Is This Tool?
This converter allows users to change pressure measurements from pound-force per square inch, a common imperial unit, to ton-force (long) per square inch, a legacy British pressure unit. It is useful for interpreting historical engineering data and translating pressures into compatible modern or SI units.
How to Use This Tool?
-
Enter the pressure value in pound-force per square inch (psi)
-
Select the target unit: ton-force (long) per square inch
-
Click convert to see the equivalent pressure in ton-force (long)/square inch
-
Use the results to interpret legacy engineering pressures or update designs
Key Features

Conversion depends on exact definitions of long ton and area, potentially affecting precision
-
Not standardized internationally and may vary in historical sources
Frequently Asked Questions
-
What does pound-force per square inch measure?
-
It measures pressure as the force of one pound-force applied over an area of one square inch, commonly used in engineering and everyday applications.
-
Why convert psi to ton-force (long) per square inch?
-
This conversion helps interpret or compare historical British engineering data where ton-force (long)/square inch was the standard unit.
-
Is ton-force (long) per square inch commonly used today?
-
No, it is primarily a legacy unit found in older technical documents and is not widely used in contemporary engineering.
Key Terminology
-
Pound-force per square inch (psi)
-
An imperial unit of pressure defined as one pound-force applied to an area of one square inch, widely used in engineering.
-
Ton-force (long) per square inch
-
A legacy British unit representing pressure as the force of one long ton distributed over one square inch of area.
-
Long ton
-
A British unit of weight equal to 2240 pounds, used in defining ton-force (long) per square inch.
