The exapascal is a multiple of the unit bit for Pressure. The prefix exa (symbol E) is defined in the International System of Units (SI) as a multiplier of 1.0 × 1018 (1 quintillion, short scale), and therefore 1 exapascal = 1.0 × 1018 pascals = 1000000000000000000 pascals. The exapascal has the unit symbol EPa.
The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar). It is sometimes used as a reference or standard pressure.
