How to Convert Atmospheres to Pascals

Calculators can be used to convert measurements from one unit to another

To convert a atmosphere measurement to a pascal measurement, multiply the pressure by the conversion ratio. One atmosphere is equal to 101,325 pascals, so use this simple formula to convert:

pascals = atmospheres × 101,325

The pressure in pascals is equal to the atmospheres multiplied by 101,325.

For example, here's how to convert 5 atmospheres to pascals using the formula above.
5 atm = (5 × 101,325) = 506,625 Pa

Atmospheres and pascals are both units used to measure pressure. Keep reading to learn more about each unit of measure.

Atmospheres

The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.

Atmospheres can be abbreviated as atm, for example 1 atmosphere can be written as 1 atm.

Pascals

The pascal is defined as the pressure of one newton per square meter.

The pascal is the SI derived unit for pressure in the metric system. Pascals can be abbreviated as Pa, for example 1 pascal can be written as 1 Pa.

Pascals can be expressed using the formula:
1 Pa = 1 Nm2

Pressure in pascals is equal to the force in newtons divided by the area in square meters.
