What is a poundal per square foot?

It is a unit of pressure in the foot–pound–second system defined as one poundal of force applied over one square foot of area, approximately equal to 1.48816 pascals.

Why is inch mercury referenced at 60°F?

The 60°F reference fixes the mercury density for consistent calibration and reliable pressure measurements across atmospheric and vacuum applications.

Where is this conversion useful?

This is used in meteorology, aviation altimeter settings, vacuum system gauges, and converting legacy engineering pressure data.
