About these units
Standard Atmospheres (atm): A standard atmosphere is exactly 101,325 Pa – the average air pressure at sea level.
Kilopascals (kPa): A kilopascal is 1,000 pascals. Tyre pressures in Canada and Australia are given in kPa.
Frequently asked questions
How many kilopascals are in 1 standard atmosphere?
1 standard atmosphere (atm) equals 101.325 kilopascals (kPa).
How do I convert atm to kPa?
Multiply the value in standard atmospheres by 101.325. For example, 5 atm × 101.325 = 506.625 kPa.
How do I convert kilopascals back to standard atmospheres?
Multiply by 0.009869232667 (or divide by 101.325). 1 kPa = 0.009869232667 atm.
What is a standard atmosphere?
A standard atmosphere is exactly 101,325 Pa – the average air pressure at sea level.
