What is a micropascal used for?

A micropascal measures very small pressures typically used in acoustic and underwater sound pressure level measurements.

Why do converted values from micropascal to kilogram-force per square millimeter appear very small?

Because micropascal measures tiny pressures related to sound, while kilogram-force per square millimeter corresponds to large mechanical pressures, resulting in very small numerical values after conversion.
