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 kilopascal (kPa). Kilopascal is 1000 pascal units.
How do I convert attopascal to kilopascal?
Multiply the attopascal value by 1.000000e-21. For example, 10 aPa × 1.000000e-21 = 1.000000e-20 kPa.
Is the attopascal to kilopascal 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 attopascal needs to be compared with, or reported in, kilopascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert kilopascal back to attopascal?
Yes. Multiply the kilopascal value by 1.000000e+21 to get attopascal.

About this conversion
This page converts attopascal (aPa) to kilopascal (kPa) within the pressure converter.
Attopascal is 1e-18 pascal units. Kilopascal is 1000 pascal units.
The formula is kilopascal = attopascal × 1.000000e-21, 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 attopascal values already converted to kilopascal.
