Atmosphere to PascalConverter
Instantly convert Atmosphere (atm) to Pascal (Pa). Free, accurate, and easy to use.
How to Convert Atmosphere to Pascal
To convert Atmosphere (atm) to Pascal (Pa), multiply your value by 101325.
Example: 5 atm × 101325 = 506625 Pa
What is a Atmosphere?
The standard atmosphere (atm) is defined exactly as 101,325 Pascals and represents average sea-level air pressure on Earth. It is the standard reference pressure in chemistry for gas laws (STP), and in diving to express depth pressure. Every 10 meters of seawater adds approximately 1 atm of pressure. The atmospheric pressure on Mars is only about 0.006 atm.
What is a Pascal?
The Pascal (Pa) is the SI derived unit of pressure, equal to one Newton per square meter (N/m²). It was named after French mathematician and physicist Blaise Pascal, who formulated key principles of fluid pressure in the 17th century. Because one Pascal is very small, kilopascals (kPa) and megapascals (MPa) are used in most practical contexts. Standard atmospheric pressure at sea level equals 101,325 Pascals.

Frequently Asked Questions
How do I convert Atmosphere to Pascal?
Multiply the Atmosphere value by 101325. Formula: Pa = atm × 101325. Example: 10 atm = 1013250 Pa.
How many Pascal are in one Atmosphere?
One Atmosphere (atm) equals 101325 Pascal (Pa).
How many Atmosphere are in one Pascal?
One Pascal (Pa) equals 0.00000987 Atmosphere (atm).
What is the exact conversion factor from Atmosphere to Pascal?
The conversion factor is 101325. Multiply any atm value by this number to get Pa. For the reverse, multiply by 0.00000987.
How do I convert Pascal back to Atmosphere?
Divide by 101325, or equivalently multiply by 0.00000987. Formula: atm = Pa ÷ 101325.
Is the Atmosphere-to-Pascal conversion internationally standardized?
Yes. Both units are defined by international standards (SI or the international yard/pound agreement), so the conversion factor 101325 is exact and universally agreed upon.
