Convert Pascals to Atmospheres
Pa to atm · pressure conversion
What are pascals and atmospheres?
The pascal is the SI unit of pressure, one newton per square meter. One atmosphere is the average air pressure at sea level, defined as 101,325 Pa. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert pascals to atmospheres
1 Pa = 0.00000986923 atm. To convert, multiply the number of pascals by 0.00000986923. For example, 5 Pa = 0.0000493462 atm, and 20 Pa = 0.000197385 atm. To go the other way, multiply atmospheres by 101,325 (since 1 atm = 101,325 Pa).

FAQ
What is 1 Pa in atm?
1 Pa = 0.00000986923 atm. To convert any amount, multiply the number of pascals by 0.00000986923.
How do I convert atmospheres back to pascals?
Go the other way: 1 atm = 101,325 Pa, so multiply atmospheres by 101,325 to get pascals.
Is a pascal bigger than a atmosphere?
No — 1 Pa is the smaller unit, equal to 0.00000986923 atm (it takes 101,325 Pa to make one atm).
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.
