What is an inch water (4°C)?

An inch water (4°C) is the pressure exerted by a 1-inch column of water at 4 °C under standard gravity, commonly used for low-pressure measurements.

Where is pound-force per square foot commonly used?

Pound-force per square foot is often used in US customary engineering for structural loads, wind pressures, and distributed surface stresses.

Can this conversion be used for dynamic pressure measurements?

No, this conversion is intended for hydrostatic and static pressures and may not be accurate for dynamic conditions.
