Convert pascal to attopascal
Please provide values below to convert pascal [Pa] to attopascal [aPa], or Convert attopascal to pascal.
How to Convert Pascal to Attopascal
1 Pa = 1e+18 aPa
Example: convert 15 Pa to aPa:
15 Pa = 15 × 1e+18 aPa = 1.5e+19 aPa
Pascal to Attopascal Conversion Table
| pascal | attopascal |

Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
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.
