About these units
Kilopascals (kPa): A kilopascal is 1,000 pascals. Tyre pressures in Canada and Australia are given in kPa.
Standard Atmospheres (atm): A standard atmosphere is exactly 101,325 Pa – the average air pressure at sea level.
Frequently asked questions
How many standard atmospheres are in 1 kilopascal?
1 kilopascal (kPa) equals 0.009869232667 standard atmospheres (atm).
How do I convert kPa to atm?
Multiply the value in kilopascals by 0.009869232667. For example, 5 kPa × 0.009869232667 = 0.04934616334 atm.
How do I convert standard atmospheres back to kilopascals?
Multiply by 101.325 (or divide by 0.009869232667). 1 atm = 101.325 kPa.
What is a kilopascal?
A kilopascal is 1,000 pascals. Tyre pressures in Canada and Australia are given in kPa.
