Convert psi to attopascal
Please provide values below to convert psi [psi] to attopascal [aPa], or Convert attopascal to psi.
1 psi = 6.8948e+21 aPa. To convert psi to attopascal, multiply the value by 6.8948e+21; to go the other way, divide by it (1 aPa = 1.4504e-22 psi). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 psi = 6.8948e+21 aPa
- 1 aPa = 1.4504e-22 psi
- 10 psi = 6.8948e+22 aPa
- 100 psi = 6.8948e+23 aPa
How to Convert Psi to Attopascal
1 psi = 6.89475729e+21 aPa
Example: convert 15 psi to aPa:
15 psi = 15 × 6.89475729e+21 aPa = 1.0342135935e+23 aPa

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.
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.
