Convert Atmospheres to Kilopascals
atm to kPa · pressure conversion
What are atmospheres and kilopascals?
One atmosphere is the average air pressure at sea level, defined as 101,325 Pa. A kilopascal is 1,000 pascals, commonly used for tire and weather pressure. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert atmospheres to kilopascals
1 atm = 101.325 kPa. To convert, multiply the number of atmospheres by 101.325. For example, 5 atm = 506.625 kPa, and 20 atm = 2,026.5 kPa. To go the other way, multiply kilopascals by 0.00986923 (since 1 kPa = 0.00986923 atm).

FAQ
What is 1 atm in kPa?
1 atm = 101.325 kPa. To convert any amount, multiply the number of atmospheres by 101.325.
How do I convert kilopascals back to atmospheres?
Go the other way: 1 kPa = 0.00986923 atm, so multiply kilopascals by 0.00986923 to get atmospheres.
Is a atmosphere bigger than a kilopascal?
Yes — 1 atm is the larger unit, equal to 101.325 kPa.
Are these pressure conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
