About Gigapascals
A gigapascal (GPa) = 10⁹ Pa = 10 kbar - the extreme-pressure unit for materials science and planetary physics. Bulk moduli: fused silica 72 GPa; iron 170 GPa; diamond 442 GPa (highest known). Earth's inner core: 330-360 GPa. Jupiter's core: ~40,000-70,000 GPa. NIF laser-shocked experiments create 100-100,000 GPa to reproduce planetary interior conditions. Metallic hydrogen is predicted to form above ~500 GPa and has been tentatively observed at 400-500 GPa in diamond anvil cells. 1 GPa = 10⁹ Pa = 10 kbar.
About Pascals
The pascal (Pa) is the SI unit of pressure - 1 N/m², named after Blaise Pascal (1623-1662). Standard sea-level atmosphere ≈ 101,325 Pa. One pascal is very small: roughly the pressure of a single banknote lying flat. Pascal is simultaneously the SI unit for mechanical stress and elastic modulus: structural steel Young's modulus ~200 GPa; rubber shear modulus ~0.5 MPa. Used universally in fluid mechanics, acoustics, atmospheric science, and materials engineering. 1 Pa = 1 N/m².
