What is pound-force per square inch (psi)?

Pound-force per square inch is an imperial pressure unit defined as one pound-force applied to an area of one square inch, widely used in engineering and common applications.

What does attopascal measure?

Attopascal is an SI derived pressure unit equal to 10^-18 pascal, used to describe extremely small pressures much lower than typical atmospheric or laboratory levels.

Why convert psi to attopascal?

Conversion to attopascal allows expressing common pressure values in ultra-low pressure scales needed for astrophysics, vacuum systems, and advanced scientific experiments.
