What does pound-force per square foot measure?

It measures pressure as one pound-force distributed over an area of one square foot, commonly used in US engineering for surface loads.

Why is inch water specified at 60°F?

Because water density varies with temperature, the inch water pressure unit is standardized at 60°F for consistency in measuring small pressure differences.

Can I use this conversion for temperatures other than 60°F?

Conversions involving different temperatures may require adjustments since the inch water unit depends on water density at the specified temperature.
