What does pound-force per square inch measure?

It measures pressure as one pound-force applied over an area of one square inch, commonly used in engineering and automotive contexts.

Is kilogram-force per square millimeter an SI unit?

No, kilogram-force per square millimeter is a gravitational unit and not part of the modern International System of Units.

Why convert between psi and kgf/mm²?

Converting these units is helpful in engineering and materials science where pressure values need to be expressed in different unit systems for analysis and specification.
