Convert Bars to Petapascals
Convert Bars (bar) to Petapascals (PPa) instantly and accurately.
Conversion Formula
PPa = bar × 1.000000000e-10
About Bars
A bar = exactly 100,000 Pa ≈ 0.987 atm - the world standard for industrial pressure outside North America. Hydraulic systems, pneumatic equipment, gas cylinders, dive computers, and tyre gauges in Europe and Asia use bar. Scuba diving: +1 bar per 10 m depth; at 40 m recreational limit = 5 bar absolute. European tyre pressure labels show bar alongside kPa. Industrial processes: steam at 10-50 bar; high-pressure reactors 100-300 bar; water-jet cutting 1,000-4,000 bar. 1 bar = 100,000 Pa = 14.504 psi.
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.
