Petapascal Unit | All you need to know
The petapascal (symbol: PPa) is an SI-derived unit of pressure equal to one quadrillion (1015) pascals. It is an extremely large pressure unit used primarily in astrophysics, geophysics, high-energy physics, and theoretical research involving exceptionally high pressures. The petapascal uses the SI prefix peta, representing a factor of 1015.
One petapascal is equal to 1,000 terapascals, 1,000,000 gigapascals, 1,000,000,000 megapascals, 10,000,000,000 bars, and 1×1015 pascals. Although rarely encountered outside advanced scientific research, the petapascal is part of the complete SI pressure scale.
