Convert Standard atmosphere to petapascal
Please provide values below to convert Standard atmosphere [atm] to petapascal [PPa], or Convert petapascal to Standard atmosphere.
How to Convert Standard Atmosphere to Petapascal
1 atm = 1.01325e-10 PPa
Example: convert 15 atm to PPa:
15 atm = 15 × 1.01325e-10 PPa = 1.519875e-09 PPa
Standard Atmosphere to Petapascal Conversion Table

Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
Petapascal
A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.
History/Origin
The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.
Current Use
Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
