Real-world reference

Earth's mean sea-level pressure is approximately 1 atm. Pressure doubles roughly every 10 m of seawater. In pascals, that gives you: 1 atm = 101325 Pa, 10 atm = 1013250 Pa, 100 atm = 10132500 Pa.

Frequently asked questions

How many pascals are in 1 standard atmosphere?
1 standard atmosphere equals 101325 pascals.
How do I convert standard atmospheres to pascals?
Multiply the standard atmosphere value by 101325. So x atm × 101325 = the equivalent in Pa.
What is 5 standard atmospheres in pascals?
5 standard atmospheres equals 506625 pascals.
What is 10 standard atmospheres in pascals?
10 standard atmospheres equals 1013250 pascals.
What is 100 standard atmospheres in pascals?
100 standard atmospheres equals 10132500 pascals.
How do I convert back from pascals to standard atmospheres?
Multiply the pascal value by 9.8692 × 10^−6. For example, 1 Pa = 9.8692 × 10^−6 atm.
Is the standard atmosphere bigger than the pascal?
Yes. 1 standard atmosphere is larger than 1 pascal — specifically 101325 times larger.
Are these conversion factors exact?
Yes. The factor of 101325 is derived directly from the SI definitions of standard atmosphere and pascal.

About the standard atmosphere and the pascal

The standard atmosphere

The standard atmosphere (atm) is defined as exactly 101,325 Pa. It is the conventional reference for chemistry (gas-law calculations), aviation altimetry, and historic engineering. Despite the name, it is not the actual atmospheric pressure at any single place — that varies daily.

The pascal

The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter. It is the universal unit in physics and engineering documentation. In everyday life pascals are tiny — atmospheric pressure is around 101,000 Pa — so multiples like kPa and MPa dominate practical use.
