Convert attopascal to psi
Please provide values below to convert attopascal [aPa] to psi [psi], or Convert psi to attopascal.
1 aPa = 1.4504e-22 psi. To convert attopascal to psi, multiply the value by 1.4504e-22; to go the other way, divide by it (1 psi = 6.8948e+21 aPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aPa = 1.4504e-22 psi
- 1 psi = 6.8948e+21 aPa
- 10 aPa = 1.4504e-21 psi
- 100 aPa = 1.4504e-20 psi
How to Convert Attopascal to Psi
1 aPa = 1.45037737796859e-22 psi
Example: convert 15 aPa to psi:
15 aPa = 15 × 1.45037737796859e-22 psi = 2.17556606695288e-21 psi

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.
Psi
Psi (pounds per square inch) is a unit of pressure measurement representing the force of one pound applied to an area of one square inch.
History/Origin
The psi originated in the United States as a customary unit of pressure, commonly used in engineering and industrial applications. It became standardized with the development of the imperial system of units.
Current Use
Psi is widely used today in various fields such as automotive tire pressure, plumbing, and industrial pressure measurements, especially in the United States and other countries using imperial units.
