Convert Standard atmosphere to attopascal
Please provide values below to convert Standard atmosphere [atm] to attopascal [aPa], or Convert attopascal to Standard atmosphere.
How to Convert Standard Atmosphere to Attopascal
1 atm = 1.01325e+23 aPa
Example: convert 15 atm to aPa:
15 atm = 15 × 1.01325e+23 aPa = 1.519875e+24 aPa

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.
Attopascal
The attopascal (aPa) is a unit of pressure equal to 10^-18 pascals, representing an extremely small pressure measurement.
History/Origin
The attopascal was introduced as part of the SI prefixes to denote very small quantities of pressure, but it is rarely used in practical applications due to its minuscule magnitude.
Current Use
The attopascal is primarily used in scientific research and theoretical contexts where extremely small pressure differences are relevant, although it remains largely a conceptual unit.
