Exapascal Unit | All you need to know
The exapascal (symbol: EPa) is an SI-derived unit of pressure equal to one quintillion (1018) pascals. It is an extremely large pressure unit used primarily in theoretical physics, geophysics, astrophysics, and advanced scientific research involving exceptionally high pressures. The exapascal uses the SI prefix exa, representing a factor of 1018.
One exapascal is equal to 1,000 petapascals, 1,000,000 terapascals, 1,000,000,000 gigapascals, 10,000,000,000,000 bar, and 1×1018 pascals. Although rarely encountered outside research, the exapascal is part of the complete SI pressure scale.
