Conversion Formula
Ba = GPa × 10000000000
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 Barye
The barye (Ba) is the CGS unit of pressure - 1 dyne/cm² = exactly 0.1 Pa = 1 µbar. Standard atmosphere = 1,013,250 Ba. It dominated physics and laboratory science from the mid-19th century until SI adoption. Legacy acoustic CGS literature used 1 barye (0.1 Pa) as the underwater reference pressure, creating a 100 dB offset versus the modern 1 µPa reference - a critical correction when comparing historical and modern underwater acoustics databases. Still encountered in classical fluid mechanics derivations and early 20th-century meteorological literature. 1 Ba = 0.1 Pa.
