What does a femtopascal measure?

A femtopascal measures extremely small pressures, typically used in ultra-low gas pressures or stresses in scientific and astrophysical contexts.

What applications use exapascal as a unit?

Exapascal is used to represent extraordinarily large pressures in fields such as astrophysics, including stellar interiors, neutron-star modeling, and high-energy physics.

Why is converting between femtopascal and exapascal challenging?

The conversion spans an enormous difference in magnitude (10³³), which may cause numerical underflow or overflow in some calculation tools.
