Convert Millibars to Petapascals
Convert Millibars (mbar) to Petapascals (PPa) instantly and accurately.
Conversion Formula
PPa = mbar × 1.000000000e-13
About Millibars
A millibar (mbar) = 100 Pa = 1 hPa - the historically dominant meteorological pressure unit. Standard sea-level pressure is 1013.25 mbar. Hurricane intensity is characterised by central pressure: Category 5 storms typically below 920 mbar (US record: 892 mbar, 1935). Upper-air analysis levels - 850, 700, 500, 300, 200 mbar - appear throughout decades of archived meteorological data. Aircraft cabins are pressurised to ~750-800 mbar at cruise altitude. 'Weather bombs' see pressure fall 24+ mbar in 24 hours. 1 mbar = 100 Pa.
About Petapascals
A petapascal (PPa) = 10¹⁵ Pa - pressures found in stellar interiors. The Sun's centre is ~25 PPa, sustained by radiation pressure from nuclear fusion balanced against gravity. White dwarf stars: ~10⁴ PPa (electron degeneracy). Neutron stars: ~10⁹-10¹⁰ PPa, where nuclear structure fails and neutrons drip from nuclei at ~4 × 10⁸ PPa (the neutron drip line). The hadron-quark phase transition in the densest neutron star cores is estimated at 10¹⁰-10¹² PPa. No laboratory experiment can approach petapascal pressures. 1 PPa = 10¹⁵ Pa.
