What does pound-force per square foot measure?

It measures pressure as one pound-force distributed uniformly over one square foot, mainly used in US customary engineering.

Why is inch mercury referenced to 60°F?

The 60°F reference fixes mercury density to ensure consistent pressure calibration and reporting.

Where is inch mercury (60°F) commonly used?

It's used in meteorology for atmospheric pressure, aviation for altimeter settings, and laboratories for vacuum measurements.
