Frequently asked questions
What is the source unit in this conversion?
The source unit is the atmosphere (atm). A standard atmosphere is exactly 101,325 pascals.
What is the destination unit in this conversion?
The destination unit is the attopascal (aPa). Attopascal is 1e-18 pascal units.
How do I convert atmosphere to attopascal?
Multiply the atmosphere value by 1.013250e+23. For example, 10 atm × 1.013250e+23 = 1.013250e+24 aPa.
Is the atmosphere to attopascal conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in atmosphere needs to be compared with, or reported in, attopascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert attopascal back to atmosphere?
Yes. Multiply the attopascal value by 9.869233e-24 to get atmosphere.

About this conversion
This page converts atmosphere (atm) to attopascal (aPa) within the pressure converter.
A standard atmosphere is exactly 101,325 pascals. Attopascal is 1e-18 pascal units.
The formula is attopascal = atmosphere × 1.013250e+23, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
Use the calculator above for instant results, or the table below for common atmosphere values already converted to attopascal.
