Please provide values below to convert decipascal [dPa] to Standard atmosphere [atm], or Convert Standard atmosphere to decipascal.
How to Convert Decipascal to Standard Atmosphere
1 dPa = 9.86923266716013e-07 atm
Example: convert 15 dPa to atm:
15 dPa = 15 × 9.86923266716013e-07 atm = 1.48038490007402e-05 atm

Decipascal
The decipascal (dPa) is a unit of pressure equal to one-tenth of a pascal, where 1 dPa = 0.1 Pa.
History/Origin
The decipascal was introduced as a metric unit to provide finer measurement options within the pressure unit system, though it is rarely used in practice due to the widespread adoption of the pascal.
Current Use
The decipascal is seldom used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific contexts or educational settings for illustrative purposes.
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.
