The zettapascal is a multiple of the unit bit for Pressure. The prefix zetta (symbol Z) is defined in the International System of Units (SI) as a multiplier of 1.0 × 1021 (1 sextillion, short scale), and therefore 1 zettapascal = 1.0 × 1021 pascals = 1000000000000000000000 pascals. The zettapascal has the unit symbol ZPa.
