– This pressure is internationally defined as 1 standard atmosphere (atm).
– 1 atm is equivalent to 101,325 Pascals (Pa), which is the SI unit of pressure.
– 1 bar is another unit of pressure, equal to 100,000 Pa, which is slightly less than 1 atm.
– Pascal is the SI unit of pressure (N/m²).
– Poise is a unit of dynamic viscosity.
