Real-world reference

Earth's mean sea-level pressure is approximately 1 atm. Pressure doubles roughly every 10 m of seawater. In kilopascals, that gives you: 1 atm = 101.325 kPa, 10 atm = 1013.25 kPa, 100 atm = 10132.5 kPa.

Frequently asked questions

How many kilopascals are in 1 standard atmosphere?
1 standard atmosphere equals 101.325 kilopascals.
How do I convert standard atmospheres to kilopascals?
Multiply the standard atmosphere value by 101.325. So x atm × 101.325 = the equivalent in kPa.
What is 5 standard atmospheres in kilopascals?
5 standard atmospheres equals 506.625 kilopascals.
What is 10 standard atmospheres in kilopascals?
10 standard atmospheres equals 1013.25 kilopascals.
What is 100 standard atmospheres in kilopascals?
100 standard atmospheres equals 10132.5 kilopascals.
How do I convert back from kilopascals to standard atmospheres?
Multiply the kilopascal value by 0.00986923. For example, 1 kPa = 0.00986923 atm.
Is the standard atmosphere bigger than the kilopascal?
Yes. 1 standard atmosphere is larger than 1 kilopascal — specifically 101.325 times larger.
Are these conversion factors exact?
Yes. The factor of 101.325 is derived directly from the SI definitions of standard atmosphere and kilopascal.

About the standard atmosphere and the kilopascal

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 kilopascal

The kilopascal (kPa) equals exactly 1,000 pascals. It is the standard pressure unit in modern meteorology, engineering specs outside the US, and most non-US tire-pressure recommendations.
