What does a femtopascal measure?

A femtopascal measures extremely low pressure, expressing force per unit area in values as small as 10⁻¹⁵ pascals, used mainly in astrophysics and vacuum science.

Why convert femtopascal to kilogram-force per square millimeter?

Converting allows relating ultra-low pressure measurements from scientific research to pressure or stress units common in engineering and materials testing.

Is kilogram-force per square millimeter an SI unit?

No, kilogram-force per square millimeter is a non-SI gravitational unit that is still used in some engineering contexts and older technical literature.
