What does pound-force per square foot measure?

It quantifies pressure as one pound-force evenly distributed over one square foot, commonly used in US customary engineering.

When should I use millimeter water (4°C) as a pressure unit?

Use millimeter water (4°C) for very small pressures like those in low-pressure sensors, HVAC static measurements, or laboratory conditions.

Can I use this converter for all pressure ranges?

This converter is best suited for typical ranges; very high or very low pressures might affect accuracy due to unit scaling and physical variations.

Key Terminology

Pound-force/square foot: A unit of pressure representing one pound-force spread evenly across an area of one square foot, used in US customary systems.
Millimeter water (4°C): A pressure unit based on the hydrostatic pressure exerted by a 1 mm column of water at 4 degrees Celsius under standard gravity.
Hydrostatic pressure: The pressure exerted by a fluid at rest due to the force of gravity.

Quick Knowledge Check

What does one pound-force per square foot represent?

One pound-force over one square inch

One pound-force distributed across one square foot

One kilogram-force over one square foot

Millimeter water (4°C) is used to measure which kind of pressure?

High pressures in structural loads

Very small hydrostatic pressures

Atmospheric pressure variations

Why might precision loss occur when converting between these units?

Because pound-force/square foot is temperature dependent

Due to differences in magnitude and temperature/gravity effects on millimeter water
