What is pound-force per square foot?

Pound-force per square foot is a pressure unit used in US customary engineering, defined as one pound-force evenly distributed across an area of one square foot.

Why use standard atmosphere as a pressure unit?

Standard atmosphere represents average atmospheric pressure at sea level and serves as a common reference pressure in physics, chemistry, and engineering.

Can I use this tool for converting pressure units other than pound-force/square foot and standard atmosphere?

No, this tool specifically converts between pound-force per square foot and standard atmosphere only.
