Convert pascal to attopascal
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
Attopascal
The attopascal (symbol: aPa) is a unit of pressure equal to 10⁻¹⁸ pascals, formed by applying the SI prefix atto- to the pascal. It is the smallest named SI-prefixed pascal unit in common use and represents pressures far below anything currently achievable in laboratory vacuum systems. One attopascal equals 10⁻¹⁸ N/m².
