Frequently asked questions
What is the source unit in this conversion?
The source unit is the Attopascal (aPa). Attopascal is 1e-18 pascal units.
What is the destination unit in this conversion?
The destination unit is the Torr (Torr). A torr is 1/760 standard atmosphere.
How do I convert Attopascal to Torr?
Multiply the Attopascal value by 0. For example, 10 aPa × 0 = 0 Torr.
Is the Attopascal to Torr conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Attopascal needs to be compared with, or reported in, Torr, such as in engineering, scientific, or industrial calculations.
Can I convert Torr back to Attopascal?
Yes. Multiply the Torr value by 1.33322e+20 to get Attopascal.

About this conversion
This page converts Attopascal (aPa) to Torr (Torr) within the engineering converter.
Attopascal is 1e-18 pascal units. A torr is 1/760 standard atmosphere.
The formula is Torr = aPa × 0, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
