Atmospheres to Pascals Converter

To convert a measurement in atmospheres to pascals, multiply the value by 101,325. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 atm to pascals: 5 × 101,325 = 506,625 Pa.

A standard atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals, approximating average sea-level air pressure. Defined by the International Union of Pure and Applied Chemistry as a reference pressure, the atmosphere is widely used in chemistry and physics to describe conditions relative to sea level.

Common uses of atmospheres include: Chemistry reference conditions (STP); Diving and hyperbaric medicine; Physics gas-law calculations; Describing high-pressure environments.

A pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 N/m²). Named after the French mathematician and physicist Blaise Pascal, the unit was adopted by the International System of Units in 1971. It is a small unit, so everyday pressures are usually expressed in kilopascals or bars.

Common uses of pascals include: Scientific and engineering stress calculations; Meteorological reporting (via hectopascals); Material strength and tensile testing; Fluid mechanics and aerodynamics.

Here are some common values converted:

1 atm = 101,325 Pa 5 atm = 506,625 Pa 10 atm = 1,013,250 Pa 50 atm = 5,066,250 Pa 100 atm = 10,132,500 Pa
