What is a gigapascal used for?

A gigapascal measures very high pressures or mechanical stresses in fields like materials science, engineering, and geophysics.

When should I use petapascal units?

Petapascals are used primarily to express extraordinarily large pressures in astrophysics, high-energy physics experiments, and shock physics.

How do gigapascal and petapascal units relate?

One gigapascal equals 0.000001 petapascals, reflecting that petapascals represent pressures millions of times larger.
