Common Use Cases
-
Updating legacy British engineering pressure values to modern SI and small units
-
Converting industrial press pressure ratings for contemporary instrumentation
-
Measuring low-pressure differences in HVAC duct and filter systems
-
Calibration of pressure sensors and manometers in ventilation and cleanroom environments
Tips & Best Practices
-
Verify temperature conditions when using inch water (60°F) due to water density variations
-
Use this tool to translate historical pressure data for modern engineering analysis
-
Ensure unit selections match your source and target pressures to avoid errors
Limitations
-
Ton-force (long)/square inch is a legacy unit not common in current standards
-
Inch water (60°F) pressures depend on temperature, requiring control or correction for precision
Frequently Asked Questions
-
What is a ton-force (long)/square inch?
-
It is a pressure unit representing the force of one long ton distributed over one square inch of area, used mainly in historical British engineering contexts.
-
Why is inch water specified at 60°F?
-
Because water density changes with temperature, specifying 60°F standardizes the pressure measurement for consistent results.
-
When should I use this converter?
-
Use this converter when you need to translate legacy high-pressure imperial values into low-pressure units for modern HVAC, instrumentation, or engineering applications.
Key Terminology
-
Ton-force (long)/square inch
-
A legacy imperial pressure unit defined as the force of one long ton (2240 lb) applied per square inch of area.
-
Inch water (60°F) [inAq]
-
A pressure unit based on the hydrostatic pressure of a 1-inch water column at 60 °F used to measure very small pressure differences.
-
Legacy Unit
-
A measurement unit historically used but less common in modern applications.
