Zettapascal Unit | All you need to know
The zettapascal (symbol: ZPa) is an SI-derived unit of pressure equal to one sextillion (1021) pascals. It is an extremely large pressure unit used in astrophysics, cosmology, geophysics, and theoretical scientific research involving immense pressures. The zettapascal uses the SI prefix zetta, representing a factor of 1021.
One zettapascal is equal to 1,000 exapascals, 1,000,000 petapascals, 1,000,000,000 terapascals, 10,000,000,000,000,000 bars, and 1×1021 pascals. The zettapascal is part of the complete SI pressure scale for expressing extraordinarily large pressure values.
