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.
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, now defined as exactly 1/760 of a standard atmosphere. Thus one torr is exactly 101325/760 pascals (~133.3 Pa).
