Convert Attopascal to Bar
Attopascal
An attopascal (aPa) is a unit of pressure in the International System of Units (SI), equal to 10⁻¹⁸ pascals (Pa). A pascal is defined as one newton per square meter (N/m²). The attopascal is used in various scientific and engineering contexts.
The term "attopascal" combines the SI prefix "atto-", representing 10⁻¹⁸, and the unit "pascal," named after Blaise Pascal, a French mathematician and physicist known for his contributions to the study of pressure and fluid mechanics. The prefix "atto-" comes from the Danish word "atten," meaning "eighteen." The attopascal is used in contexts where pressures are extremely low.
Bar
A bar is a unit of pressure defined as 100,000 pascals (Pa). It is not an SI unit, but it is widely used in many fields, including meteorology, oceanography, and engineering.
The bar was introduced by the Norwegian meteorologist Vilhelm Bjerknes, and it is derived from the Greek word "baros," meaning weight. Although the bar is not an SI unit, it is accepted for use with the SI.
