Convert Atmospheres to Pascals
atm to Pa · pressure conversion
What are atmospheres and pascals?
One atmosphere is the average air pressure at sea level, defined as 101,325 Pa. The pascal is the SI unit of pressure, one newton per square meter. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert atmospheres to pascals
1 atm = 101,325 Pa. To convert, multiply the number of atmospheres by 101,325. For example, 5 atm = 506,625 Pa, and 20 atm = 2,026,500 Pa. To go the other way, multiply pascals by 0.00000986923 (since 1 Pa = 0.00000986923 atm).

FAQ
What is 1 atm in Pa?
1 atm = 101,325 Pa. To convert any amount, multiply the number of atmospheres by 101,325.
How do I convert pascals back to atmospheres?
Go the other way: 1 Pa = 0.00000986923 atm, so multiply pascals by 0.00000986923 to get atmospheres.
Is a atmosphere bigger than a pascal?
Yes — 1 atm is the larger unit, equal to 101,325 Pa.
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.
