What does one ton-force (long)/square foot represent?

It is the pressure resulting from one long ton-force applied over a single square foot, approximately equal to 2240 pounds-force per square foot.

Why is inch water (4°C) used as a pressure unit?

Inch water (4°C) is a small pressure unit generated by a column of water at 4°C and standard gravity, ideal for measuring low pressures with fine precision.

When should I convert from ton-force (long)/square foot to inch water (4°C)?

Conversions are useful when translating heavy-load or historical pressure values into units suitable for low-pressure measurements and modern instrumentation calibration.
