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.
The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one newton per square metre.
