About Torr

The torr is defined as exactly 1/760 of a standard atmosphere ≈ 133.322 Pa - effectively replacing mmHg with an exact definition. Named after Evangelista Torricelli (1608-1647), inventor of the barometer. Vacuum science universally uses torr: rough vacuum 760-1 torr; medium vacuum 1-10⁻³ torr; high vacuum 10⁻³-10⁻⁷ torr; ultra-high vacuum below 10⁻⁹ torr. UHV systems for surface science, particle accelerator beam tubes, and space simulation chambers reach 10⁻¹¹-10⁻¹² torr. 1 torr = 133.322 Pa.

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.
