The yottapascal is a multiple of the unit bit for Pressure. The prefix yotta (symbol Y) is defined in the International System of Units (SI) as a multiplier of 1.0 × 1024 (1 septillion, short scale), and therefore 1 yottapascal = 1.0 × 1024 pascals = 1000000000000000000000000 pascals. The yottapascal has the unit symbol YPa.
