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

It measures pressure exerted by one long ton-force (2240 pounds-force) distributed over one square foot, typically used for large structural loads.

When should I use millimeter water (4°C) as a pressure unit?

Millimeter water (4°C) is appropriate for measuring very small pressures, such as those encountered in low-pressure sensor calibration, HVAC static pressure, and laboratory hydrostatics.

Why are the converted values so large when going from ton-force (long)/square foot to millimeter water?

Because ton-force (long)/square foot represents large pressures, while millimeter water measures very small pressures, the numeric conversion yields large values due to the difference in scale.
