What does inch mercury (32°F) represent?

It is a pressure unit defined by the pressure exerted by a one-inch column of mercury at 32°F under standard gravity.

What is ton-force (long)/square inch used for?

This legacy unit expresses pressure as the force of one long ton distributed over one square inch, commonly seen in historical British engineering.

Is this conversion suitable for all engineering calculations?

While helpful, this conversion should be applied carefully considering the temperature-specific and legacy nature of the units involved.
