Convert Standard atmosphere to nanopascal
Please provide values below to convert Standard atmosphere [atm] to nanopascal [nPa], or Convert nanopascal to Standard atmosphere.
How to Convert Standard Atmosphere to Nanopascal
1 atm = 101325000000000 nPa
Example: convert 15 atm to nPa:
15 atm = 15 × 101325000000000 nPa = 1.519875e+15 nPa

Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
