AttopascalaPa
Target UnitThe attopascal (aPa) is a subunit of pressure that is defined as one quintillionth of a pascal (Pa), which is the SI unit of pressure. Specifically, 1 attopascal equals 10^-18 pascals. The pascal itself is defined as one newton per square meter. This extremely small unit of pressure is utilized in high-precision scientific measurements, particularly in fields such as quantum physics and astrophysics, where minute variations in pressure can have significant implications.
Current Use
The attopascal is predominantly used in specialized scientific research and high-precision instruments. In fields such as quantum mechanics, it is essential for measuring the pressures achieved in ultrahigh vacuum environments, where the pressures can be exceptionally low. The attopascal is also relevant in astrophysics for studying the atmospheres of distant planets or the pressure conditions within stellar environments.
Fun Fact
The attopascal is so small that it is often used in theoretical physics rather than practical applications.

Definition
The attopascal (aPa) is a subunit of pressure that is defined as one quintillionth of a pascal (Pa), which is the SI unit of pressure. Specifically, 1 attopascal equals 10^-18 pascals. The pascal itself is defined as one newton per square meter. This extremely small unit of pressure is utilized in high-precision scientific measurements, particularly in fields such as quantum physics and astrophysics, where minute variations in pressure can have significant implications.
History & Origin
The attopascal was introduced to provide a more convenient way to express extremely low pressures that are relevant in certain scientific fields. The pascal, named after the French mathematician and physicist Blaise Pascal, was adopted as the SI unit for pressure in 1971. The prefix 'atto-' is derived from the Greek word 'atto', meaning 'eighteen', and was officially added to the International System of Units in 1960. This prefix allows scientists to express measurements of pressure that are otherwise cumbersome at such low values.
Etymology: The term 'attopascal' combines the prefix 'atto-', representing 10^-18, with 'pascal', the unit of pressure.
Current Use
The attopascal is predominantly used in specialized scientific research and high-precision instruments. In fields such as quantum mechanics, it is essential for measuring the pressures achieved in ultrahigh vacuum environments, where the pressures can be exceptionally low. The attopascal is also relevant in astrophysics for studying the atmospheres of distant planets or the pressure conditions within stellar environments.
💡 Fun Facts
- •The attopascal is so small that it is often used in theoretical physics rather than practical applications.
- •One attopascal is equivalent to less than one billionth of a standard atmospheric pressure.
- •The prefix 'atto-' was derived from the Danish word 'at', meaning 'eighteen', reflecting its power of ten.
