What is the definition of Standard atmosphere?

Standard atmosphere (atm) is a pressure unit defined as exactly 101,325 pascals (Pa), approximately equal to average sea-level atmospheric pressure.

What contexts use the Exapascal unit for pressure?

Exapascal (EPa) is used mainly in astrophysics, planetary science, and high-energy physics to describe extremely large pressure values.

Why are converted values often very small in this tool?

Because 1 atm equals a very small fraction of 1 EPa, converted values appear as very small numbers and typically use scientific notation.
