Formula

How to convert Atmospheres to Kilopascals

To convert atmospheres to kilopascals, multiply by 101.325. One atmosphere equals 101.325 kPa, and one kilopascal equals 0.00986923 atm.

  1. Take the value in atmospheres — for example 7.5 atm.
  2. Multiply by 101.325 (the number of kilopascals in one atmosphere).
  3. 7.5 × 101.325 = 759.9375 kPa.

Quick mental estimate: Multiply the number of atmospheres by 101 (within 0.3% of the exact answer).

About converting Atmospheres to Kilopascals

Atmospheres (atm) and Kilopascals (kPa) are both units of pressure. The exact factor is 1 atm = 101.325 kPa, so multiply by 101.325 to go from atmospheres to kilopascals (or divide to go back).

The units

Atmospheres (atm)

The standard atmosphere: exactly 101,325 Pa, average sea-level air pressure.

Used for: Chemistry, diving and physics.

Kilopascals (kPa)

1,000 pascals.

Used for: Tyre pressure in Canada/Australia, weather and engineering.

The bar (100,000 Pa) and the standard atmosphere (101,325 Pa) are exact; psi is derived from the pound-force and the inch, so its factor is a rounded value of an exact fraction.

Frequently asked questions

5 answers
How many kilopascals are in one atmosphere?
One atmosphere equals 101.325 kilopascals.
How do I convert atmospheres to kilopascals?
Multiply the number of atmospheres by 101.325. For example, 10 atmospheres = 1,013.25 kilopascals.
What is 5 atmospheres in kilopascals?
5 atmospheres is 506.625 kilopascals.
Is a atmosphere bigger than a kilopascal?
Yes. One atmosphere equals 101.325 kilopascals, so it is 101.325 times larger.
How many kilopascals is a typical car tyre?
A typical car tyre is 220.6322 kilopascals (2.177471 atmospheres).
